Question

How do you solve `5f + 4= 5( t - 3) + 4f + 3`?

Answer 1

`f=-4`

Explanation:

`"distribute the bracket on the right side of the equation"`

`5f+4=5f-15+4f+3`

`rArr5f+4=f-12`

`"subtract f from both sides"`

`5f-f+4=cancel(f)cancel(-f)-12`

`rArr4f+4=-12`

`"subtract 4 from both sides"`

`4fcancel(+4)cancel(-4)=-12-4`

`rArr4f=-16`

`"divide both sides by 4"`

`(cancel(4) f)/cancel(4)=(-16)/4`

`rArrf=-4`
