Question

How do you solve `-3(4 + x) = 15`?

Answer 1

x=-9

Explanation:

`-3(4+x)=15`

Multiply every 4 and x by -3
`-12-3x=15`

Carry over -12 to the right side of the equal sign and add it to 15 and cancel out -12 on the other side:
`-3x=15+12`
`-3x=27`

Divide 27 by -3 and cancel out -3 on the other side:
`-3x/-3=27/-3`

The answer is x=-9
