make v the subject of the formulae:
v=2v+3u
we will be happy to critique your thinking.
To make v the subject of the formula v=2v+3u, you need to isolate v on one side of the equation. Here's how you can do it step by step:
1. Start with the formula: v = 2v + 3u.
2. To get rid of the 2v term on the right side, subtract 2v from both sides of the equation:
v - 2v = 2v - 2v + 3u.
Simplifying the left side gives: -v = 3u.
3. To isolate v, multiply both sides of the equation by -1:
-1 * (-v) = -1 * 3u.
This gives: v = -3u.
So, the subject v can be obtained by rewriting the formula as v = -3u.
