Answer:

B.) 8

Step-by-step explanation:

3r - 6 = 18

First, we take -6 to the other side of the equals to sign (=), where it changes to +6.

3r = 18+6

Now we add the LHS.

3r = 24

Now, we take 3 to the other side of =, where it will represent the denominator.

r = [tex]\frac{24}{3}[/tex]

We now solve the fraction which on dividing, comes as 8.

r = 8.
