Solve the following system of equations:

−2x + 3y = 5
y = 3x + 4

Substitute the second equation into the first equation for y:

-2x + 3(3x + 4) = 5

Simplify and solve for x:

7x + 12 = 5

7x = -7

x = -1

Now substitute x = -1 into one of the original equations (let's use the second one) and solve for y:

y = 3(-1) + 4

y = 1

Therefore, the solution to the system of equations is x = -1 and y = 1.
