Question

Como resolver a equação -7. (x-3)=x +5

Answer 1

`x=2`

Explanation:

`-7(x-3)=x+5`

Distribute the
`-7` into
`(x-3)`:

`-7x+21=x+5`

Subtract
`x` from both sides of the equation:

`-8x+21=5`

Subtract
`21` from both sides of the equation:

`-8x=-16`

Divide both sides of the equation by the coefficient of
`x`, which is
`-8`:

`x=2`

Check your work by substituting
`2` into the initial equation:

`-7(2-3)=2+5`

`-14+21=2+5`

`7=7`

The answer is correct!
