Solve the system by the method of your choice. Identify systems with no solutions and systems with infinitely many solutions, using set notation to express their solutions:
x + y = 3
-2 + y = -3


(0 ,-5)
(0 , 0)
(-2 ,-1)
(-2,-3)

  • calculus -

    x + y = 3 should be - 3

  • calculus -

    If -2+y = -3, then y = -1
    If also x+y = -3, then
    x-1 = -3 and x = -2
    (-2,-1) is the answer

  • calculus -

    thanks that's what I had I just wasn't sure if -2 + y = -3 (-2,-1) if I multipied -2(-2, -1)
