Question

solve for u in terms of r, s, and t.
t = s - r + u
u =

Explanation:

Step1: Isolate the term with \( u \)

We start with the equation \( t = s - r + u \). To isolate \( u \), we need to move the other terms to the left side. We can do this by subtracting \( s \) and adding \( r \) to both sides of the equation.
\( t - s + r = u \)

Step2: Rearrange the equation

We can rewrite the left - hand side to get the expression for \( u \). The equation \( t - s + r = u \) can also be written as \( u=t - s + r \) or \( u=t + r - s \) (by rearranging the terms).

Answer:

\( t + r - s \) (or \( t - s + r \))
