Answer:
Step-by-step explanation:
This one is easy, because the coefficient of x is the same in both equations. You can eliminate the x terms by subtracting one equation from the other.
Multiply the first equation by -1:
-6x - 5y = 39
Add it to the second equation:
-6x - 5y = 39
6x + 7y = 75
--------------------
0x + 2y = 114, so y = 57
Then substitute 57 for y in one of the equations and solve for x:
6x + 7(57) = 75
x = -54
