Question

solve for u.
5u + 15 = 80
simplify your answer as much as possible.
u =

Explanation:

Step1: Subtract 15 from both sides

To isolate the term with \( u \), we subtract 15 from both sides of the equation \( 5u + 15 = 80 \). This gives us \( 5u + 15 - 15 = 80 - 15 \), which simplifies to \( 5u = 65 \).

Step2: Divide both sides by 5

Now, to solve for \( u \), we divide both sides of the equation \( 5u = 65 \) by 5. So, \( \frac{5u}{5} = \frac{65}{5} \), which simplifies to \( u = 13 \).

Answer:

\( u = 13 \)
