x = \square
submit

Explanation:

Step1: Subtract 7 from both sides

To isolate the term with \( x \), we subtract 7 from both sides of the equation \( 2x + 7 = 15 \). This gives us \( 2x + 7 - 7 = 15 - 7 \), which simplifies to \( 2x = 8 \).

Step2: Divide both sides by 2

To solve for \( x \), we divide both sides of the equation \( 2x = 8 \) by 2. So, \( \frac{2x}{2} = \frac{8}{2} \), which simplifies to \( x = 4 \).

Answer:

\( x = 4 \)
