Which ordered pair is a solution of the equation?

y - 4 = 7 (x - 6)

Choose 1 answer:

A. Only 5,4

B. Only 6,5

C both 5,4 and 6,5

D. Neither

It will be D. Neither, because when you plug in 5 for x and 4 for y, the left side will equal 0, while the right side equals 7 (5-6) = 7 (-1) = - 7, which does not equal 0 on the left side. If you use 6 for x and 5 for y, the left side will be 1 (5-4) and the right side will equal 0, 7 (6-6) = 7 (0) = 0, which does not equal to 1
