b=2A+a
b is equal to 2 cap A plus A
b=12A−a
b is equal to 1 half cap A minus A
b=12A+a
b is equal to 1 half cap A plus A
b=2A−a
b is equal to 2 times A minus a
To solve for b in the equation A=12(a+b), we can follow these steps:
1. Start with the given equation: A = 12(a + b).
2. Expand the parentheses by multiplying 12 with both terms inside: A = 12a + 12b.
3. Move the term with b to one side of the equation by subtracting 12a from both sides: A - 12a = 12b.
4. Simplify the left side of the equation: A - 12a = b.
5. Therefore, b is equal to A - 12a.
So, the correct answer is b = A - 12a.
