Answer:
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.
Answer:
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
