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 = \(\frac{24}{3}\)
We now solve the fraction which on dividing, comes as 8.
r = 8.
