Question

Solve the systems of equations by Elimination. Find the solution.

-x+y=9
x+2y=6

Answer 1

(-4,5)

Explanation:

-X and X cancel each other out so your're left with

Y=9

2Y=6

Add the like terms together to get 3Y=15

so Y=5.

Then plug in y into one of the equations to get x.

-x+5=9

-x=4

X=-4

So the solution is (-4,5)
