Question

What is the solution to this equation?

2(5х + 8) = 6х + 20

А. x = -1
в. х = 1
с. x= 9
D. х = -9​

Answer 1

B

Explanation:

Given

2(5x + 8) = 6x + 20 ← distribute parenthesis on left side

10x + 16 = 6x + 20 ( subtract 6x from both sides )

4x + 16 = 20 ( subtract 16 from both sides )

4x = 4 ( divide both sides by 4 )

x = 1 → B
