Question

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

Answer 1

u=-r+s-t

Explanation:

Step 1: Flip the equation.

r+t+u=s

Step 2: Add -r to both sides.

t+u=-r+s

Step 3: Add -t to both sides.

u=-r+s-t

Answer 2

Explanation:

s = r + u + t

First, subtract r and t from both sides of the equation:

s - r - t = u

So, u in terms of r, s, and t is:

u = s - r - t
