Question

Negative 8 minus the product of three and a number is 19

Answer 1

The number is -9.

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
