Question

What is the value of y in the solution to the system of equations?

1/3x +1/4 = 1

2x -3y = -30


A. -8

B. -3

C. 3

D. 8

Answer 1

The correct answer is D. 8

Explanation:

In order to find this, solve by multiplying the top equation by -6. Then add the equations together to get the x values to cancel. Then you may solve for y.

-2x - 3/2y = -6

2x - 3y = -30

--------------------

9/2y = -36

y = 8
