Question

4x + 7x - 2 + 5x - 10 find the value of x

Answer 1

x = 4/5

Explanation:

1) Group like terms

4x + 7x + 5x - 2 - 10 = x

2) Add similar elements

16x - 2 - 10 = x

3) Subtract

16x - 12 = x

4) Add 12 to both sides

16x - 12 + 12 = x + 12

5) Simplify

16x = x + 12

6) Subtract x from both sides

16x - x = x + 12 - x

7) Simplify

15x = 12

8) Divide both sides by 15

15x/15 = 12/15

9) Simplify

x = 4/5
