Answer:

y = 9 1/3 or 8 if the first equation is 1/3x + 1/4y = 1.

Step-by-step explanation:

1/3x + 1/4y = 2

    2x - 3y = -30

Multiply the first equation by -6:

- 2x - 3/2y = -12  

Adding the last 2 equations:

-9/2 y = -42

y = -42 * -2/9

y = 9 1/3.

If the first equation is 1/3x + 1/4 y = 1

then y = -36 * -2/9

= 8.
