102=8a+5a-3a

I add 8a and 5a first to get 13 and then add 3?

  • Math - ,

    No.

    Subtract 3a.

    102 = 10a

  • Math - ,

    8a+5a=13a=3a=10a Divide 102/10?

  • Math - ,

    Or would the answer be 10a because 8a 5a and 3a are all like terms

  • Math - ,

    To find the value of a,divide both sides by 10.

    10a = 102
    a = 102 / 10
    a = 10.2
