Equation calculator solve for x

Instructions: Use this step-by-step calculator to solve for x from a linear equation that you provide. Please type a valid linear equation in the box provided below. More about this solve for x calculator Traditionally, you have to solve equations, and the most common setting is to solve equations when there is only one variable. But it also could be the case that you want to solve an equation when more than one variable is present. In that case, you say that you solve for that variable, as oppose to solving for any other variable present. The case of a linear equation, with two variables \(x\) and \(y\) is one of the simplest cases you can have in which you can solve for one of the variables, \(x\) in this case. How to use this x solver It is very simple: Step 1: The first thing you need to do is to type a linear equation like "2x - 3y = 3" or something like "x - 2y = 4" Step 2: One a valid linear equation is provided, the calculator will try to find the value of x, and it will solve for x if possible, showing all the steps Step 3: The final result is an expression of x as a function of y, if that is possible, or reaching the conclusion that there is no solution for x How do you solve for X? The idea is simple: you need to manipulate the equation using algebraically valid

Calculator Use This calculator will solve for the exponent n in the exponential equation xn = y, stated x raised to the nth power equals y. Enter x and y and this calculator will solve for the exponent n using log(). Since taking the log() of negative numbers causes calculation errors they are not allowed. How to solve for exponents For xn = y; solve for n by taking the log of both sides of the equation: For: \( x^n = y \) Take the log of both sides: \( \log_{}x^n = \log_{}y \) By identity we get: \( n \cdot \log_{}x = \log_{}y \) Dividing both sides by log x: \( n = \dfrac{\log_{}y}{\log_{}x} \) Find the exponent of a number For the equation 3n = 81 where 3 is called the base and n is called the exponent, find the value of the exponent n using logarithms. For: \( 3^n = 81 \) Take the log of both sides: \( \log_{}3^n = \log_{}81 \) By identity we get: \( n \cdot \log_{}3 = \log_{}81 \) Dividing both sides by log 3: \( n = \dfrac{\log_{}81}{\log_{}3} \) Using a calculator we can find that log 81 ≈ 1.9085 and log 3 ≈ 0.4771 then our equation becomes: \( n = \dfrac{\log_{}81}{\log_{}3} \approx \dfrac{1.9085}{0.4771} \approx 4 \) Checking our answer 34 = 81. Since taking the log() of negative numbers, 0 or 1 causes calculation errors we have provided some answers by definition and not actual calculations.

To use the substitution calculator, enter the linear equation separated by "," and press calculate button Substitution Method CalculatorSubstitution method calculator is an online tool that is used to solve the system of linear equations. The substitution calculator will give a step-by-step solution.What is the Substitution Method?The substitution method is a mathematical technique that is used to solve a system of equations. In this method, isolate one variable from one equation (say “x”), and its value is substituted into the other equation of the same system.Then evaluate the value of the other variable (say “y”) by substituting the equation using algebraic operation. This value is put into the first equation to evaluate the value of the first variable.How to use the substitution method to solve linear equations?Here is an example of solving a system of equations to explain the working of the substitution method.Example:Solve the given system of equations using the Substitution method.x + 2y = -3x - 3y = 2Solution:Step 1: write the above equation and give the name eq (i) & eq (ii).x + 2y = -3------> (i)x - 3y = 2--------> (ii)Step 2: Solve the eq (i) for “x”.x + 2y = -3x = -3 - 2yStep 3: Substitute the above value in eq (ii) and Simplify for “y”.(-3 - 2y) –3 y = 2-3 - 2y – 3y = 2- 3– 5y = 2– 5y = 2 + 3– 5y = 5y = 5/(-5)y = - 1Step 4: Put the above value of “y” in step 2 and simplify.Put y = - 1x = -3 - 2yx = -3 – 2(-1)x = -3 + 2x = - 1Hence,x = -1, y = - 1 is the solution of the given system of linear equations.Some other examples System of linear equationsResultsx+y=5 ; x+2y=7x=3, y =2-x-7y=-1 ; x-2y=-8x=−6, y=12x + y = 7 ;3x - 4y = 1x=38/11, y=1/112x – y = 3 ; x + 2y = 2x=8/5, y=1/5x-3y = -43 ; 2x+2y=-41x=-209/8, y=45/8
