Solve for b in the following equation: A=12(a+b)

A. b=12A−a

B. b=12A+a

C. b=2A−a

D. b=2A+a

1 answer

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

Starting with the given equation:

A = 12(a+b)

Distribute the 12 to both terms inside the parentheses:

A = 12a + 12b

Subtract 12a from both sides of the equation to isolate the term containing b:

A - 12a = 12b

Now divide both sides of the equation by 12:

(A - 12a)/12 = b

Simplifying the left side:

A/12 - 12a/12 = b

A/12 - a = b

Thus, the solution is:

B. b = A/12 - a
