Question

How do you solve `(x+4)/-7 = -3`?

Answer 1

`x=17`

Explanation:

`"multiply both sides of the equation by "-7`

`cancel(-7)^1xx(x+4)/cancel(-7)^1=-7xx-3`

`rArrx+4=21`

`"subtract 4 from both sides"`

`xcancel(+4)cancel(-4)=21-4`

`rArrx=17" is the solution"`

Answer 2

Multiply both sides by `-7`
`(x+4)/cancel(-7) cancel(-7) = -3xx-7`
Minus into minus = plus
`x+4=21`
Subtract both sides by 4
`xcancel(+4) cancel (-4) = 21-4`
`x=17`
