Question

How do you solve `5y+3y+16=48`?

Answer 1

`y=4`

Explanation:

`5y+3y+16=48`

collect like terms on LHS

`8y+16=48`

subtract `16` from both sides

`8y+cancel(16-16)=48-16`

`8y=32`

`:.y=32/8`

`y=4`

Answer 2

`y=4`

Explanation:

`5y+3y+16=48`

`rArr8y+16=48`

`"subtract 16 from both sides"`

`8ycancel(+16)cancel(-16)=48-16`

`rArr8y=32`

`"divide both sides by 8"`

`(cancel(8) y)/cancel(8)=32/8`

`rArry=4" is the solution"`
