    A=3

    First you would collect the like terms

    -5a+21-6

    Move constant to the right

    -5a=21-6

    Subtract the numbers

    -5a=15

    Divide both sides by - 5 and there ya go

    4a + 23 - 9a - 17 = 21 ... simplify

    -5a + 6 = 21

    -5a = 21 - 6

    -5a = 15

    a = - 15/5

    a = - 3 <==
