Question

solve for u.

u - 1 = 1

u =

submit

Explanation:

Step1: Add 1 to both sides

To isolate \( u \), we add 1 to both sides of the equation \( u - 1 = 1 \). This gives us \( u - 1 + 1 = 1 + 1 \).

Step2: Simplify both sides

Simplifying the left side, \( -1 + 1 = 0 \), so we have \( u = 1 + 1 \). Simplifying the right side, \( 1 + 1 = 2 \).

Answer:

\( 2 \)
