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

Mathematics
1 answer:
valina [46]2 years ago
3 0

Answer:

x = 4/5

Step-by-step 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
