Question

Solve the system by using elimination or elimination with multiplication.
x + y = 16 and x + y = -2

Answer 1

To use elimination, you need to add the equations and make one variable add up to zero. Since you have x in both equations, multiply the second equation by -1 to get -x. Then when you add the equations, the x's will be eliminated becasue x + (-x ) = 0
x + y = 16
x + y = -2

Rewrite first equation. Below that write second equation multiplied by -1:
x + y = 16
-x - y = 2 (add equations)
---------------
0 + 0 = 18
0 = 18
Since 0 is not equal to 18, this system of equations has no solution.
