Add 5, and then divide by 2.
Subtract 5, and then multiply by 2.

Answer 1

To solve the equation \( \frac{x}{2} - 5 = 20 \), you can follow these steps in order:

1. Add 5 to both sides of the equation to isolate the term with \( x \). \[ \frac{x}{2} - 5 + 5 = 20 + 5 \] This simplifies to: \[ \frac{x}{2} = 25 \]

2. Multiply both sides by 2 to solve for \( x \). \[ 2 \times \frac{x}{2} = 25 \times 2 \] This simplifies to: \[ x = 50 \]

So, the correct steps in order to solve the equation \( \frac{x}{2} - 5 = 20 \) are Add 5, and then multiply by 2.
