Question

solve for u.
$u + 7.9 = 17.4$
$u = \square$

Explanation:

Step1: Subtract 7.9 from both sides

To solve for \( u \), we need to isolate \( u \) on one side of the equation. We can do this by subtracting 7.9 from both sides of the equation \( u + 7.9 = 17.4 \).
\[
u + 7.9 - 7.9 = 17.4 - 7.9
\]

Step2: Simplify both sides

Simplifying the left side, \( u + 7.9 - 7.9 \) gives \( u \). Simplifying the right side, \( 17.4 - 7.9 = 9.5 \).
\[
u = 9.5
\]

Answer:

\( 9.5 \)
