Question

what value of s is a solution to this equation?
s - 2 = 9
s = 10 s = 11

Explanation:

Step1: Solve the equation \( s - 2 = 9 \)

To solve for \( s \), we add 2 to both sides of the equation. So, \( s = 9 + 2 \).

Step2: Calculate the value

\( 9 + 2 = 11 \), so \( s = 11 \). We can also check by substituting back: for \( s = 10 \), \( 10 - 2 = 8
eq 9 \); for \( s = 11 \), \( 11 - 2 = 9 \), which matches the equation.

Answer:

s = 11
