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

1/3 x + 1/4y = 1

2x - 3y = - 30

1 Solve for x in 1/3x+1/4y=1

X=3 (1-y/4)

2 Substitute x=3 (1-y/4) into 2x-3y=-30

6-9y/2 = - 30

3 Solve for y in 6-9y/2=-30

y=8

4 Substitute y=8 into x=3 (1-y/4)

x=-3

5 Therefore,

x=-3

y=8
