Question

How do you solve `3(x+6) = x-6`?

Answer 1

`x=-12`

Explanation:

Given:
`color(white)("XXX")3(x+6)=x-6`

Distribute the multiplication on the left side
`color(white)("XXX")3x+18=x-6`

Subtract `18` from both sides:
`color(white)("XXX")3x=x-24`

Subtract `x` from both sides
`color(white)("XXX")2x=-24`

Divide both sides by `2`
`color(white)("XXX")x=-12`
