Answer:
A - 7
Step-by-step explanation:
These angles are corresponding, meaning they are congruent. Therefore it is simple algebra.
16x - 7 = 105
16x = 112
112/16 = 7
x=7
Solve for x in -7x - 8y = 9
x = -9 + 8y/7
Substitute x = -9 + 8y/7 into -4x + 9y = -22
4(9 + 8y)/7 + 9y = -22
Solve for y in 4(9 + 8y)/7 + 9y = -22
y = -2
Substitute y = -2 into x = -9 + 8y/7
x = 1
Thus,
<u>x = 1</u>
<u>y = -2</u>
