7(x - 4) + 4x = 71

7x - 28 + 4x = 71

11x - 28 = 71

11x = 71 + 28

11x = 99

x = 99/11

x = 9

7x - 28 + 4x = 71

11x - 28 = 71

11x = 71 + 28

11x = 99

x = 99/11

x = 9

Score:
Solve 7(x - 4) + 4x = 71.
**Weegy:** 4x - 5 > 15 , add 5 to both sides: 4x > 20. Now, divide both sides by 4: x > 5. Your answer is x > 5. (More)
