If it's not what You are looking for type in the equation solver your own equation and let us solve it.
Simplifying (x + -4) * 2 = 2x Reorder the terms: (-4 + x) * 2 = 2x Reorder the terms for easier multiplication: 2(-4 + x) = 2x (-4 * 2 + x * 2) = 2x (-8 + 2x) = 2x Add '-2x' to each side of the equation. -8 + 2x + -2x = 2x + -2x Combine like terms: 2x + -2x = 0 -8 + 0 = 2x + -2x -8 = 2x + -2x Combine like terms: 2x + -2x = 0 -8 = 0 Solving -8 = 0 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
