Question

1. 5s + 4s + 16 = -56

Explanation:

Step1: Combine like terms

Combine the \(5s\) and \(4s\) terms. So \(5s + 4s=9s\), and the equation becomes \(9s + 16=-56\).

Step2: Subtract 16 from both sides

Subtract 16 from each side of the equation to isolate the term with \(s\). So \(9s+16 - 16=-56 - 16\), which simplifies to \(9s=-72\).

Step3: Divide by 9

Divide both sides of the equation by 9 to solve for \(s\). So \(\frac{9s}{9}=\frac{-72}{9}\), which gives \(s = - 8\).

Answer:

\(s=-8\)
