In the equation 2x + 2y = 120, how do I divide both sides by 2? Will I divide both 2x and 2y by 2 to equal 60?

    Yes, the distributive rule applies here, so divide all terms by 2.

    [2x + 2y]/2 = 120/2

    2x/2 + 2y/2 = 60

    x + y = 60

    Divide across by 2:

    x+y = 60

    2x+2y=120

    divide throughout by 2

    (2x/2)+(2y/2)=(120/2)

    so it is

    x+y=60

    yes, if you divide one term by 2, you must divide all terms by 2.
