To solve the equation: First, subtract 9 from both sides of the equation. Second, divide both sides of the equation by -10

Step-by-step explanation:

We are subtracting from both sides because we need to do the inverse, and the inverse of adding 9 is subtracting it.

Same with the -10. We need to do the inverse, and the inverse of multiplying by -10 is dividing by it.

First: Subtract 9 from both sides of the equation. Second: Divide both sides of the equation by -10

Step-by-step explanation:

because 9 is positive, to get rid of it you need to subtract it.

after than, you would get -10x = -30

you would then divide it by -10 because you need to get x by itself

x = -3
