Question

How do you solve X + x/7 + (x +x/7 ) = 60?

Answer 1

`x+ (x)/(7) +(x+ (x)/(7) )=60`

Remove parentheses (a)= a


`x+ (x)/(7) +x+ (x)/(7)`

Group like terms:


`x+ (x)/(7) +x+x`

Add similar elements:


`(x)/(7) + (x)/(7) =2 (x)/(7)`


`= 2 (x)/(7) +x+x`

Add similar elements:


`x+x = 2x`


`2 (x)/(7) +2x`

Multiply
`2 (x)/(7)`


`= (2x)/(7) +2x`


`(2x)/(7) +2x = 60`

Multiply both sides by 7 :


`(2x)/(7) *7+2x*7 = 60*7`


`16x = 420`


`x = 420 / 16`


`x = (105)/(4)`

hope this helps!
