Question 74366
Solve this problem using the substitution method 
4x - y = -3
y - 3 = 4x
-------------
Solve the 2nd equation for y: y=4x+3
Substitute that into the 1st equation to solve for "x":
4x-(4x+3)=-3
4x-4x-3=-3
-3=-3
This means the two equations are dependent which means one
is a multiple of the other.  It also means that every point
on the line y=4x+3 is a solution for the system of equations.
