• Solve System by Substitution 5 
  • Solve the system by substitution.  x - 5y = 2-7x - 6y = 27
  • Solve the system by substitution. x - 4y = -312x - 4y = -34
  • Solve the system by substitution.x - y2 = 0x - 25 = 0
  • Solve the system by substitution.x + y = 17x - y = 1
  • Solve the system by substitution.y - x2 = -3xy = x + 5
