Question

23/40
9 = 2s + 1
-4
4
5
3.5

Explanation:

Step1: Subtract 1 from both sides

To isolate the term with \( s \), we subtract 1 from both sides of the equation \( 9 = 2s + 1 \). This gives us \( 9 - 1 = 2s + 1 - 1 \), which simplifies to \( 8 = 2s \).

Step2: Divide both sides by 2

Now, to solve for \( s \), we divide both sides of the equation \( 8 = 2s \) by 2. So, \( \frac{8}{2} = \frac{2s}{2} \), which simplifies to \( s = 4 \).

Answer:
