Question

Solve for u in terms of r, s, and t.
t=
1
2
u(s+r)
u=

Answer 1

To solve for \( u \) in terms of \( r \), \( s \), and \( t \) from the equation:

\[
t = \frac{1}{2} u(s + r)
\]

we can start by isolating \( u \).

1. Multiply both sides of the equation by 2 to eliminate the fraction:

\[
2t = u(s + r)
\]

2. Now, divide both sides by \( (s + r) \):

\[
u = \frac{2t}{s + r}
\]

Thus, \( u \) in terms of \( r \), \( s \), and \( t \) is:

\[
u = \frac{2t}{s + r}
\]
