Answer:
x=8
y=7
Step-by-step explanation:
We can figure out x because opposite angles are equal.
7x-2=11x-34
-2+34=11x-7x
32=4x
8=x
We can figure out y because we know the value of x now, and we know supplementary angles equal 180.
18y=180-(11x-34)
18y=180-(11(8)-34)
18y=180-(88-34)
18y=180-54
18y=126
y=7
