Answer:

x = -3 and y = 8

Explanation:

1/3 (-3) + 1/4 (8) = 1

Answer:

The value of y in the solution to the system of equations is:


y=8

Explanation:

We have the following system of equations


(1)/(3)x+(1)/(4)y=1\\2x-3y=-30

To solve the system multiply the first equation by -6 and add it to the second equation


-6*(1)/(3)x-6*(1)/(4)y=-6


-2x-(3)/(2)y=-6

+


2x-3y=-30

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


0 - 4.5y=-36


y=(-36)/(-4,5)


y=8
