Sure, here is the step-by-step solution for the system of equations using substitution:

1. The first equation is x = 8–4. Simplify this to get x = 4.

2. Substitute x = 4 into the second equation. The second equation is -3y = -8 - 4x. Replace x with 4 to get -3y = -8 - 4(4).

3. Simplify the equation to get -3y = -8 - 16, which simplifies further to -3y = -24.

4. Solve for y by dividing both sides of the equation by -3. This gives y = -24 / -3 = 8.

So, the solution to the system of equations is x = 4 and y = 8.
