Question

What is the solution to this equation?

9x - 4(x - 2) = x+ 20
O A. x= 7
O B. x = 3
O c. X=-3
O D. x=-7

Answer 1

B

Explanation:

9x - 4(x - 2) = x + 20

9x - 4x + 8 = x + 20 (Distribute 4)

5x + 8 = x + 20 (Combine like terms)

4x + 8 = 20 (Subtract x from both sides)

4x = 12 (Subtract 8 from both sides)

x = 3 (Divide equation by 4)
