Question 8

b=2A−a

To solve for b in the equation A=12(a+b), we can start by isolating the term with b on one side of the equation.

Let's begin by moving the term 12b to the right side by subtracting it from both sides of the equation:

A - 12b = 12(a + b) - 12b

Simplifying the right side of the equation gives us:

A - 12b = 12a + 12b - 12b

The -12b terms on the right side cancel out, leaving us with:

A - 12b = 12a

Next, we can move the -12b term to the left side by adding 12b to both sides of the equation:

A - 12b + 12b = 12a + 12b

Simplifying the left side of the equation gives us:

A = 12a + 12b

To isolate the term with b, we can subtract 12a from both sides of the equation:

A - 12a = 12a + 12b - 12a

Simplifying the right side of the equation gives us:

A - 12a = 12b

Finally, we can divide both sides of the equation by 12 to solve for b:

b = (A - 12a) / 12

Therefore, the correct answer is b = (A - 12a) / 12.
