2. solve for u.\n1 = u + 5

2. solve for u.\n1 = u + 5
Answer
Explanation:
Step1: Isolate the variable u
Subtract 5 from both sides of the equation. $1 - 5=u + 5-5$
Step2: Simplify both sides
On the left - hand side, $1 - 5=-4$, and on the right - hand side, $u+(5 - 5)=u$. So, $u=-4$
Answer:
$u = - 4$
