3x - x = 28 - 12
2x = 16
x = 16/2
x = 8

x = 8

Answer 2

Simplifying 3(x + 4) + -1x = 28 Reorder the terms: 3(4 + x) + -1x = 28 (4 * 3 + x * 3) + -1x = 28 (12 + 3x) + -1x = 28 Combine like terms: 3x + -1x = 2x 12 + 2x = 28 Solving 12 + 2x = 28 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + 2x = 28 + -12 Combine like terms: 12 + -12 = 0 0 + 2x = 28 + -12 2x = 28 + -12 Combine like terms: 28 + -12 = 16 2x = 16 Divide each side by '2'. x = 8 Simplifying x = 8
