Question

solve 7s = 28.
s = __

Explanation:

Step1: Isolate the variable \( s \)

To solve for \( s \) in the equation \( 7s = 28 \), we divide both sides of the equation by 7. This is because the coefficient of \( s \) is 7, and dividing by the coefficient will isolate \( s \).
\[
\frac{7s}{7} = \frac{28}{7}
\]

Step2: Simplify both sides

Simplifying the left side, \( \frac{7s}{7} \) simplifies to \( s \). Simplifying the right side, \( \frac{28}{7} \) equals 4.
\[
s = 4
\]

Answer:

\( s = 4 \)
