Question

1. 2x - 4 = 7

Explanation:

Step1: Add 4 to both sides

To isolate the term with \( x \), we add 4 to both sides of the equation \( 2x - 4 = 7 \). This gives us \( 2x - 4 + 4 = 7 + 4 \), which simplifies to \( 2x = 11 \).

Step2: Divide by 2

To solve for \( x \), we divide both sides of the equation \( 2x = 11 \) by 2. So, \( \frac{2x}{2} = \frac{11}{2} \), which simplifies to \( x = \frac{11}{2} \) or \( x = 5.5 \).

Answer:

\( x = \frac{11}{2} \) (or \( x = 5.5 \))
