Question

8 + \frac{x}{3} = 13

Explanation:

Step1: Subtract 8 from both sides

To isolate the term with \( x \), we subtract 8 from both sides of the equation \( 8 + \frac{x}{3} = 13 \). This gives us \( \frac{x}{3}=13 - 8 \).
Calculating the right - hand side: \( 13-8 = 5 \), so the equation becomes \( \frac{x}{3}=5 \).

Step2: Multiply both sides by 3

To solve for \( x \), we multiply both sides of the equation \( \frac{x}{3}=5 \) by 3. Using the property of equality, if \( \frac{x}{3}=5 \), then \( x = 5\times3 \).
Calculating the right - hand side: \( 5\times3=15 \).

Answer:

\( x = 15 \)
