Solution by Steps

step 1

Combine like terms by adding $4s$ to both sides of the equation $8 - 4s = s + 13$

step 2

The equation becomes $8 = 5s + 13$

step 3

Subtract $13$ from both sides to isolate terms with $s$ on one side: $8 - 13 = 5s$

step 4

Simplify the left side: $-5 = 5s$

step 5

Divide both sides by $5$ to solve for $s$: $s = -1$

Answer

$s = -1$

Key Concept

Solving linear equations with variables on both sides

Explanation

To solve for $s$, we combined like terms and isolated the variable on one side of the equation, then divided by the coefficient of $s$ to find its value.
