  1. #1 has a typo

    you provide no pairs for 2,3,4,5

    For #6, you know that x = y+3
    So, y = x-3
    I assume one of the graphs works for that.

    For the rest, work to isolate the variable

    #7
    -4 = g+1
    you want g all alone, so get rid of the 1 with subtraction
    -4-1 = g+1-1
    -5 = g

    the others work the same way. Surely your text has many examples. I know google can provide many more.
