Answer:
The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.
Step-by-step explanation:
Data
Equation 1 x - 4y = -17
Equation 2 y = 4x + 8
Solve for y
Equation 1 y = -x/-4 - 17/-4
y = x/4 + 17/4
Equation 2 y = 4x + 8
See the graph below
These lines cross in point (-1, 4), so that is the only one solution.
If the lines were the same line they would have infinite solutions
