Answer:
x = 11, y = 17
Step-by-step explanation:
Note that
9x - 4 = 8x + 7 ( vertical angles )
Subtract 8x from both sides
x - 4 = 7 ( add 4 to both sides )
x = 11
and
7y - 34 = 5y ( vertical angles )
Subtract 5y from both sides )
2y - 34 = 0 ( add 34 to both sides )
2y = 34 ( divide both sides by 2 )
y = 17
