-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2

3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0

3x + 11 = x + 3 2x = -8 x = -4

3x + 8 = 23 Subtract 8 from both sides: 3x = 15 Divide both sides by 3: x = 5

3x + 5 = -20. First, subtract 5 from both sides of the equation: 3x + 5 - 5 = -20 - 5; and simplify: 3x = -25. Then divide both sides by 3: 3x / 3 = -25 / 3; and simplify: x = -8 1/3 (or -8.33)
