Answer:
Simplifying 2x + -7 = 9x + 8 Reorder the terms: -7 + 2x = 9x + 8 Reorder the terms: -7 + 2x = 8 + 9x Solving -7 + 2x = 8 + 9x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9x' to each side of the equation. -7 + 2x + -9x = 8 + 9x + -9x Combine like terms: 2x + -9x = -7x -7 + -7x = 8 + 9x + -9x Combine like terms: 9x + -9x = 0 -7 + -7x = 8 + 0 -7 + -7x = 8 Add '7' to each side of the equation. -7 + 7 + -7x = 8 + 7 Combine like terms: -7 + 7 = 0 0 + -7x = 8 + 7 -7x = 8 + 7 Combine like terms: 8 + 7 = 15 -7x = 15 Divide each side by '-7'. x = -2.142857143 Simplifying x = -2.142857143
