Answer is this system of equations has NO solution
Step by step
4x + 2y = 8
Arrange in y intercept form
2y = -4x + 8
Divide all by 2 to solve
y = -2x + 4
-4x -2y = 3
Arrange in y intercept form
2y = -4x -3
Divide all by 2 to solve
y = -2x -3/2
These equations have the same slope (2) with different y intercepts, so they are parallel lines. Parallel lines never intersect so there is no solution.
