Solve the system by graphing.
-2x + y = 2
3x + y = -3
Solve the systems using substitution.
3x - y = 18
y = x - 4
Solve the system using the graphing method.
x - 3y = -3
5x - 3y = 9
Solve the system using the substitution method.
x - y = 3
2x - 3y = -3
Solve using the multiplication/elimination method.
3x - 5y = -4
4x + 2y = 12
Solve using the multiplication/elimination method.
3x + 6y = 6
2x + 3y = 5
