Question

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 

10x - 8y = -2
9x + 8y = 59

Answer 1

Correct answer is (d) (3,4)

Answer 2

Just add the equations in order to eliminate y, 
19x = 57
x = 57/19
x = 3

Substitute it in equation 1, 
10(3) - 8y = -2
-8y = -2 - 30
y = -32/-8
y = 4

In short, Your Answer would be Option D) (3,4)

Hope this helps!
