solve for b

Question

3 (b + a) = r

Answer 1

To solve for b, we need to isolate it on one side of the equation.

3(b + a) = r

First, distribute the 3 to the terms inside the parentheses:

3b + 3a = r

Next, subtract 3a from both sides of the equation:

3b = r - 3a

Finally, divide both sides of the equation by 3:

b = (r - 3a) / 3

Therefore, the solution for b is (r - 3a) / 3.
