Question

$\frac{x}{2} - 5 = 7$
$\underline{\quad +5 \quad \quad +5}$
$\frac{x}{2} = 13$
$x = 26$

Explanation:

Step1: Add 5 to both sides

$\frac{x}{2} - 5 + 5 = 7 + 5$
$\frac{x}{2} = 12$

Step2: Multiply by 2 on both sides

$\frac{x}{2} \times 2 = 12 \times 2$

Answer:

$x = 24$

Note: The original calculation had an error in Step1: $7+5=12$, not 13. The corrected solution gives the accurate result.
