Simplifying 2x + 5 + 6x + -1 = 120
Reorder the terms: 5 + -1 + 2x + 6x = 120
Combine like terms: 5 + -1 = 4 4 + 2x + 6x = 120
Combine like terms: 2x + 6x = 8x 4 + 8x = 120 Solving 4 + 8x = 120
Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + 8x = 120 + -4 Combine like terms: 4 + -4 = 0 0 + 8x = 120 + -4 8x = 120 + -4
Combine like terms: 120 + -4 = 116 8x = 116 Divide each side by '8'. x = 14.5 Simplifying x = 14.5
