Question

Find the values of x and y.

Answer 1

x = 11, y = 17

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
