SOLVE THE SYSTEM USING SUBSTITUTION MATH X4Y=49 3Y4Y=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.
