probably wants you to find what numbers will work for x and y in both equations
add the two equations together
5x-5x+2y+7y=10+8
9y=18
divide both sdies by 9
y=2
subsitute into first equation
5x+2(2)=10
5x+4=10
subtract 4 from both sides
5x=6
divide both sdies by 5
x=6/5
so the asnwer is x=6/5 and y=2
