Linear Equation

Question

x + 4 = 4(3x - 2)

Answer 1

x + 4 = 4(3x - 2)

x + 4 = 12x - 8         distribute

4 = 11x - 8               subtract x from both sides

12 = 11x                   add 8 to both sides

12/11 = x                 divide both sides by 11

Answer 2

1. x + 4 = 4(3x - 2)

2. x + 4 = 4(3x) - 4(2)

3. x + 4 = 12x - 8

4. x - x + 4 = 12x - x - 8

5. 4 = 11x - 8

6. 4 + 8 = 11x - 8 + 8

7. 12 = 11x 

8. 12/11 = x
