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
35x10y=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.
