Question

A.) 6
B.) 8
C.) 18
D.) 24

Answer 1

The Answer is 8!! :)

Answer 2

B.) 8

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 =
`(24)/(3)`

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

r = 8.
