Answer
\( u = -5 \)
Solution
1. Start with the given equation:
\[
u + 7 = 2
\]
2. Subtract \(7\) from both sides to isolate \(u\):
\[
u + 7 - 7 = 2 - 7
\]
3. Simplify both sides:
\[
u = -5
\]
Thus, the solution is:
\[
u = -5
\]

Explain 
Simplify this solution The Deep Dive
To solve for \( u \), we need to isolate \( u \) on one side of the equation. Start with the equation: \[ u + 7 = 2 \] Now, subtract 7 from both sides: \[ u = 2 - 7 \] This simplifies to: \[ u = -5 \] So, \( u = -5 \). Remember, checking your solution is key! Plug \( u \) back into the original equation to ensure it balances: \[ -5 + 7 = 2 \] And indeed, it does! Finding that \( u = -5 \) not only solves the equation but reinforces your confidence in algebra.
