Answer:
u = v - 1
Step-by-step explanation:
I'm guessing the formula you've given me is m = m(v - u), and I'm going to solve it that way. If it's actually different, let me know so I can redo the answer! :)
So, we have the equation m = m(v - u) and we're trying to make u the subject, or isolate it on one side of the equation. Right now, it's being subtracted from v and then multiplied by m. Let's start by dividing both sides of the equation by m so we can stop multiplying (v - u) by m.
m = m(v - u)
m/m = m(v-u)/m
1 = v - u
Now, our equation is pretty simple, but our u is still being subtracted from v, so we should add a u to both sides.
1 = v - u
1 + u = v - u + u
1 + u = v
Now, we're adding 1 to u, so let's go ahead and subtract 1 from both sides.
1 + u = v
1 - 1 + u = v - 1
u = v - 1
And we now we have u as the subject of our formula.
Hopefully that was helpful! :)
