Answer:
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
