Answer:
I believe y = 90°
Step-by-step explanation:
70 + 110 = 180, so you know that both sides are the same angle. The angle of the two straight lines must be 90°
When you multiply the first equation by 3, you get:
3 × 3x = 9x
3 × y = 3y (but when added, that part gets eliminated)
3 × 3 = 9
So you end up with
9x + 3y = 9
x - 3y = -2
(add)
10x = 7
So your answer is B. 10x = 7. I hope this helps!
