Elimination involves multiplying one or more equations to either eliminate the x's or y's.

Multiplying the top equation by 2 and the bottom equation by 5 will eliminate the y's.

10x+10y=-14

35x-10y=85

Now add the equations together.

45x=71

Divide both sides by 45 to solve by x.

x=?

Now plug that number into any of the equations to figure out what y is. Post your answer if you'd like it checked.
