Final answer:
The question seems to contain a typo or confusion, but to answer the question of solving for b in the expression "m + 3Gb = qb", one would subtract m from both sides, factor out b, and then divide by the remaining coefficient to isolate b.
Step-by-step explanation:
The student's question involves solving an equation for the variable b. It appears to involve a typo or a misunderstanding, as it mixes the money quantity equation (MV = PQ) with an algebraic expression without context. To address the question as presented, we'll set aside the money quantity equation and focus on the given expression "m + 3Gb = qb".
Here's how to solve for b:
- First, we need to isolate the terms with b on one side of the equation. If the expression was meant to be "m + 3Gb = qb", then we would move the term "m" to the other side by subtracting it from both sides, resulting in "3Gb = qb - m".
- Secondly, we would factor b out from the terms on the left side, assuming "G" is a constant, which would result in "b(3G - q) = -m".
- Finally, we divide both sides by "3G - q" to solve for b, assuming "3G - q" is not zero. This results in "b = -m / (3G - q)".
Note that we're making some assumptions about the equation's form, as the original question lacks clarity.
