Answer:

Explanation:

The formula in the response bar seems incorrect. The question asks for a value of A 3 times that of B.

That means A = 3B

(7x-6) = 3(3x + 2) [The formula in the response box has 3(7x-6) = (3x + 2)]

7x - 6 = 9x + 6

-2x = 12

x = -6

A: (7x-6)

(-42-6) = -48

B: (3x + 2)

(-18 + 2) = -16

Does A = 3B?

(-48) = 3*(-16) ??

YES
