Aim #55 HW: Practice with Systems of Equations
Solve the system of equations below graphically. Check your solution!
1)
y = -x + 2
-x + y = -2
2)
y = 2x + 6
-2x + y = 6
3) Solve the system of equations algebraically using substitution. Check your solution.
y=x–7
2x + y = 8
4) Solve the system of equations algebraically using elimination. Check your solution.
3x + 6y = 6
2x – 3y = 4
