Question

-2c = -18 a. c= -9 b. c= -36 c. c= 9 d. c= 36

Answer 1

-2c = - 18

All you need to do is divided both sides by (-2)

Now you can re-write:

-2c/-2 = -18/-2

As you know -2/-2 = 1

             and -18/-2=9

so c =9

Answer is C. c = 9

   

Answer 2

All you have to do is solve for c look at the following steps :)

Step 1. Divide both sides by $-2$

$c= \frac{-18}{-2}$

Step 2. Simplify $\frac{18}{-2}$ to $- \frac{18}{2}$

$c= \frac{18}{2}$

Step 3. Simplify $\frac{18}{2}$ to $9$

$c=9$

Done! :) Your answer is C. c=9
