Question

Please explain how to do this

Answer 1

`(35)/(52)=n`

Explanation:

`(1)/(3)(5n-1)=2(1-n)+(1)/(5)n`

`(5)/(3)n-(1)/(3)=2-2n+(1)/(5)n`

`(5)/(3)n-(1)/(3)=2-(9)/(5)n`

`-(1)/(3)=2-(52)/(15)n` (-1/3 - 2 = -1/3 - 6/3 = -7/3)

`-(7)/(3)=-(52)/(15)n` (multiply by reciprocal -15/52)

`(105)/(156)=n`

`(35)/(52)=n`
