How The Solve for x Works

Using The Calculator

• Enter the expression assuming all the expression are arranged to the left hand side of the equation
• Only one variable is allowed to used this calculator to work effectively and as efficient as it can be.
• Hit the equal orange button to generate quick answer without steps but simple expansion if it contains a non-linear equation.

Inside the Calculator’s Brain

Solving Linear Equations

• If you want to solve for any linear equations in this form 4/x = 2/5, rewrite the expression so that 2/5 is over to the left hand side like this  4/x – 2/5
• If you are working with even a complex linear equation in this form 4(2x – 3)-2(x-4) = 3(x-3)-1, all you do is moved the expression after the equal sign (=) over to the left hand side, so it looks like this 4(2x – 3) -2(x-4) – 3(x-3)+1

Solving Quadratic Equations

• You can any quadratic equations in any form without entering equal to zero. A quadratic equation with highest power of unknown quantity of 2 such as x ^2 – 3x +1 = 0 can be rewritten as x ^2 – 3x +1 where the conjunction operator sign ^ raises the power or index or variable x.
• If you have x^2 – 4x = 0, rewrite as x^2 – 4x  to solve for x
• If you have an equation in this form (x + 2)^2 = 16, rewrite as (x + 2)^2  – 16

Solving Cubic Equations

A quadratic equation with highest power of unknown quantity of 3 such as x ^3 – 3x^2 + 9x +1

• Follow the same procedure to solve for x variable in any cubic equations
