Question

How do you solve `(18-x)/-9=-5`?

Answer 1

`x=-27`

Explanation:

The first step is to multiply both sides of the equation by - 9 to eliminate the fraction.

`cancel(-9)^1xx(18-x)/cancel(-9)^1=(-9xx-5)`

`rArr18-x=45`

subtract 18 from both sides.

`cancel(18)cancel(-18)-x=45-18`

`rArr-x=27`

multiply both sides by - 1.

`-1xx-x=-1xx27`

`rArrx=-27" is the solution"`
