Question

Solve for y
y+y/a=b, if a≠1

Answer 1

y =
`(ab)/(2)`

given
`(y+y)/(a)` = b, that is

`(2y)/(a)` = b ( multiply both sides by a )

2y = ab ( divide both sides by 2 )

y =
`(ab)/(2)`

Answer 2

`(y+y)/(a) = b` Multiple "a" on both sides

`(y + y)/(a) (a) = b(a)`

y + y = ab

2y = ab Divide 2 on both sides

`(2y)/(2) =(ab)/(2)`

`y = (ab)/(2)`
