Solution for 9=5+x-25 equation: Simplifying 9 = 5 + x + -25 Reorder the terms: 9 = 5 + -25 + x Combine like terms: 5 + -25 = -20 9 = -20 + x Solving 9 = -20 + x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x' to each side of the equation. 9 + -1x = -20 + x + -1x Combine like terms: x + -1x = 0 9 + -1x = -20 + 0 9 + -1x = -20 Add '-9' to each side of the equation. 9 + -9 + -1x = -20 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = -20 + -9 -1x = -20 + -9 Combine like terms: -20 + -9 = -29 -1x = -29 Divide each side by '-1'. x = 29 Simplifying x = 29
