The triangle tells us that 8x - 4 is equal to 4x + 16 we set them equal to eachother 8x - 4 = 4x + 16 and solve for x

8x - 4x - 4 = 16

4x + 4 - 4 = 16 + 4

4x = 20

x = 5

Then you plug the x value in for x on all 3 of the problems.

8(5) - 4 = 36

4(5) + 16 = 36

5(5) + 7 = 32

Therefore, the correct answer should be B
