Question

1. s - 1 = 10

Explanation:

Step1: Add 1 to both sides

To solve for \( s \) in the equation \( s - 1 = 10 \), we add 1 to both sides of the equation. This is based on the addition property of equality, which states that if we add the same number to both sides of an equation, the equality still holds. So we have:
\( s - 1 + 1 = 10 + 1 \)

Step2: Simplify both sides

Simplifying the left - hand side, \( - 1+1 = 0 \), so we are left with \( s \). Simplifying the right - hand side, \( 10 + 1=11 \). So \( s = 11 \).

Answer:

\( s = 11 \)
