102=8a+5a3a
I add 8a and 5a first to get 13 and then add 3?

No.
Subtract 3a.
102 = 10a

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

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

Math  Ms. Sue, Saturday, November 23, 2013 at 1:22pm
To find the value of a,divide both sides by 10.
10a = 102
a = 102 / 10
a = 10.2
