Question

How do you solve `\frac { 6a + 6} { 3} = - 14`?

Answer 1

`a=-8`

Explanation:

`\frac{6a+6}{3}=-14`

`{6a}/3+6/3=-14`

`2a+2=-14`

`2a=-14-2`

`2a=-16`

`a=-16/2`

`a=-8`

Answer 2

`a=-8`

Explanation:

`"multiply both sides by 3"`

`cancel(3)xx(6a+6)/cancel(3)=3xx-14`

`6a+6=-42`

`"subtract 6 from both sides"`

`6a=-42-6=-48`

`"divide both sides by 6"`

`a=(-48)/6=-8`
