Given h(x)=-x-4h(x)=−x−4, solve for xx when h(x)=9h(x)=9.

Step-by-step explanation:

Given , solve for x when .

First we need to figure out what number multiplied by 9 is equal to 9. This number is 1.

Therefore, we know that h(x) should be equal to 1 in order for 9 times h(x) to equal 9.

Create an equation where h(x) = 1.

Solve this equation by adding 4 to both sides of the equation.

Divide both sides of the equation by -1 to isolate x.

Check your answer by substituting -5 for x back into the equation to make sure h(x) = 1.

If , then the statement   is true, verifying our answer for x is correct.
