    7q = 3 - 9

    7q = -6

    q = -6/7

    To solve for q, subtract 9 from both sides of the equation:

    7q + 9 - 9 = 3 - 9

    7q = -6

    Divide both sides of the equation by 7:

    q = -6/7

    7q+9=3.

    Subtract 9 from both sides.

    7q=3-9=-6

    then divide both sides by 7.

    q=-6/7. Hope this helps!

    7q+9=3

    Let's break this down:

    7q+9=3------ Subtract nine from both sides.

    -9 -9

    ----------------------

    7q=-6 Divide both sides by seven.

    7 7

    ---------------

    q = 6/7, or .857142857

    Hope this helps,

    Zach :)
