Answer:
The number is -9.
Step-by-step explanation:
I set it up like this:
(-8) - 3x = 19
Then you add 8 to both sides of the equation in order to get rid of the negative 8.
(-8) + 8 - 3x = 19 + 8
After solving you would end up with this:
- 3x = 27
Then, you need to get the x by itself, so you divide by -3. In order to keep the equation equal though, you need to also divide the right side of the equation by -3.
- 3x ÷ -3 = 27 ÷ -3
Your final answer after solving would be:
x = -9
