    Well the reason im asking is because i forgot my math journal and i don't know what to do because i forgot.

    Here's the Question: 4z+12=7z-9

    Please write out the steps so i can do the rest.

    4z+12= 7z-9

    4z=7z-21

    -3z=-21

    z=7

    PEMDAS is your friend

    put like terms together

    4z + 12 = 7z - 9
    -4z -4z

    12 = 3z - 9
    +9 +9

    21 = 3z

    divide both sides by 3

    21/3 = 3z/3

    7 = z

    el fin

    EDIT: bah, dammit, I just wasted 2 minutes typing that out, oh well

    i still don't really understand i will just have to figure it out by myself because I have to write it out the way the teacher does it or else he will mark it wrong.

    8y+2y=6y+16
    Move all the y terms to one side.
    8y+2y-6y=16
    Sum up the y terms
    4y=16
    Divide by 4
    y=4
    Before you post please
    Read the sticky's Read the manual Use the search button Google it

    Drizzle's so cool he sh*ts icecubes.
