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.
-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 )
________(negative 16x and the one on the bottom both cancel out leaving you with just x then -16 divided by -32 is 2)
NOW SOVE FOR Y
( The 3y cancel out leaving you with just y and the 14 cancel out which would equal 0.)
Are these correct?
