**Answer:**

the value of x is 20 because is u add 70 + 80 + 10 + and m which is 20, u get 180

**Step-by-step explanation:**

Using the product rule, then (A) is the answer.

3 x + 9 = 44 - 2 x

subtract 9 from both sides:

3 x + 9 - 9 = 44 - 2x - 9

3 x = -2 x +35

Add 2 x to both sides:

3 x + 2 x = -2 x + 35 + 2 x

5 x = 35

Divide both sides by 5 :

5x / 5 = 35/ 5

**x = 7**
