Question

solve for b: b + 7 = 11

Explanation:

Step1: Subtract 7 from both sides

To solve for \( b \) in the equation \( b + 7 = 11 \), we use the subtraction property of equality. Subtract 7 from both sides of the equation:
\( b + 7 - 7 = 11 - 7 \)

Step2: Simplify both sides

Simplifying both sides, the left side becomes \( b \) (since \( 7 - 7 = 0 \)) and the right side becomes \( 11 - 7 = 4 \). So we have:
\( b = 4 \)

Answer:

\( 4 \)
