Let's look at question 2 first. Looking at the picture, it tells us:
AT = TX 4y - 2 = 14 4y = 14 + 2 4y = 16 y = 16 / 4 y = 4
TY = ZT 6x - 12 = 2x + 12 6x - 2x = 12 + 12 4x = 24 x = 24 / 4 x = 6
Thus, your answer is D, x=y, y=4
As for Question 7, The only reasonable answer for Question 7 is, "Consecutive angles of a parallelogram are supplementary; m<1 + m<2= 180" It fits perfectly in Reason 4 and Statement 5. In other words, your answer is D :)
