Question

7/3a-8/5+4/15a so all of them are fractions and "a" is a variebal.

Answer 1

`(39)/(15)` a -
`(8)/(5)`

Explanation:

Frist combine your like terms

`(7)/(3)` a +
`(4)/(15)` a The common denominator will be 15

`(35)/(15)` a+
`(4)/(15)` a=
`(39)/(15)`a

You cannot combine this with
`(8)/(5)` because these are not like terms.
