Question

solve for u. -2u - 5u - 17 = 25 simplify your answer as much as possible. u =

Explanation:

Step1: Combine like terms

Combine the \(u\)-terms: \(-2u - 5u=-7u\), so the equation becomes \(-7u - 17 = 25\).

Step2: Add 17 to both sides

Add 17 to each side: \(-7u - 17 + 17 = 25 + 17\), which simplifies to \(-7u = 42\).

Step3: Divide by -7

Divide both sides by \(-7\): \(\frac{-7u}{-7}=\frac{42}{-7}\), so \(u = -6\).

Answer:

\(u = -6\)
