Simplifying 25x = 125x + -7 Reorder the terms: 25x = -7 + 125x Solving 25x = -7 + 125x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-125x' to each side of the equation. 25x + -125x = -7 + 125x + -125x Combine like terms: 25x + -125x = -100x -100x = -7 + 125x + -125x Combine like terms: 125x + -125x = 0 -100x = -7 + 0 -100x = -7 Divide each side by '-100'. x = 0.07 Simplifying x = 0.07
