No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into - 4x-y=-2.
-4x - (-4x + 3) = - 2
-4x + 4x - 3 = - 2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
