    Put your varibles on one side of the = sign and your constants on the other. then you must divide both sides by 9 inorder to give you a statment y=?

    there isnt an equals sign so that would be rather pointless :)

    9y does not equal -11+7

    if anything: 9y -11+7 = 9y -4

    yes, and heres why. 5 = 5 is a true statement 8r=8r is a true statement 9y-4 = 9y-4 is a true statement solving for y? it can be any number it wants to be...thers nothing restricting its use right?

    9y-4 = 0 can be solved for y IF and only IF 9y-4 = 0

    otherwise: 9y-4 = 9y-4 its an identity

    I agree I was just putting in a = sign becaue i thought she was trying to solve for y.

    I understand :) and that would have been a good approach, except for we just dont know what to equal it to to begin with ;)
