]Hello,

I need someone to tell me if i did this problem right.

The question asked is solve for x and y show all your work.

7x+3y=14,5x+9y=10

5x+9y=10

-3(7x+3y=14) ( times -3 times 7x times 3y times 14)

-21x-9y=-42 (Subtract -21 from 5x) (9y cancel's out) (subtract 42 from 10 )

5x=9y=10

-16x=-32

________(negative 16x and the one on the bottom both cancel out leaving you with just x then -16 divided by -32 is 2)

-16 -16

ANSWER x=2

NOW SOVE FOR Y

7(2)+3y=14

14+3y=14

_____________

( The 3y cancel out leaving you with just y and the 14 cancel out which would equal 0.)

ANSWER y=0

Are these correct?
