Answer:


  • \boxed{\sf{r=18}}

Explanation:

To solve the equation, isolate the variable from one side of the equation.

-22=-40+r

First, switch sides.


\Rightarrow: \sf{-40+r=-22}

Then, you add by 40 from both sides.


\Longrightarrow: \sf{-40+r+40=-22+40}

Solve.

Add or subtract the numbers from left to right.


\Longrightarrow: \sf{-22+40=18}


\Longrightarrow: \boxed{\sf{r=18}}

  • Therefore, the correct answer is C. "r=18".

I hope this helps! Let me know if you have any questions.
