Question

20 = 1 + \frac{1}{2}x

Explanation:

Step1: Subtract 1 from both sides

To isolate the term with \( x \), we subtract 1 from both sides of the equation \( 20 = 1+\frac{1}{2}x \). This gives us \( 20 - 1=\frac{1}{2}x \), which simplifies to \( 19=\frac{1}{2}x \).

Step2: Multiply both sides by 2

To solve for \( x \), we multiply both sides of the equation \( 19=\frac{1}{2}x \) by 2. Using the property of equality, we get \( 19\times2 = x \), so \( x = 38 \).

Answer:

\( x = 38 \)
