Answer:

Explanation:
Given:
The given equation is

We solve the given equation step by step.

Now we will subtract both side of the above equation by 2 for eliminating 2 on left side.

In above equation +2 and -2 is cancelled in left side, so the equation is written as.

Now we subtract 10 - 2 = 8 in right side of above equation.


By cross multiplication we get the equation as written below.


Therefore, we get r = 32 by solved the given equation.
