-16y+5y=-11y, not -21y..I think that's your mistake
the answer is x= -2 and y= 7, this is how its done
then you plug in the y for the next equation
and thats how you get your x and y i hope that helped
Ok, so if I use the corrected number you gave, that would make y = 7.
Returning to the 2nd equation x=26-4y and substituting x for 7.
4y = 7 - 26
still does not add up, what am I doing wrong?
Ana, thank you, now I understand what I was doing wrong. I couldn't figure out how to rewrite the x=26-4y equation.
