SOLVE THE SYSTEM USING SUBSTITUTION MATH X-4Y=49 3Y-4Y=-66
Check your second equation again. It has two "Y" terms.
Did you substitute a Y for an X?
i have redone this problem over and over and i just cant seem to get it..
You did not read or understand my comment.
The equation 3Y - 4Y = -66 has probably been typed incorrectly by you.
