Question

What’s three times the difference of a number and four is -9

Answer 1

Greetings!

We can translate this into an equation:

`3(x-4)=-9`

Solve for x:
Distribute the Parenthesis.

`3x-12=-9`
Add 12 to both sides.

`(3x-12)+12=(-9)+12`

`3x=3`
Divide both sides by 3.

`(3x)/3=(3)/3`
The Answer Is:

`x=1`

Hope this helps.
