Question

I'm confused how to solve this, can someone help??

Answer 1

Hi, Mattie! :)

Follow BEDMASS.

`-7=-1+x/3`
Add 1 to both sides.

`(-7)+1=(-1+x/3)+1`

`-6=x/3`
Multiply both sides by 3.

`(-6)*3=(x/3)*3`

`-18=x`

-18=x

Hope this helps.

Answer 2

Add one on both sides of the equation. You would end up with -6=x/3. You would then cross multiply, so -6 times 3 and 1 (the denominator for -6) times x and you would get -18=x
