Question

42 = 42 + 9b

Explanation:

Step1: Subtract 42 from both sides

To solve for \( b \), we start by subtracting 42 from both sides of the equation \( 42 = 42 + 9b \). This gives us \( 42 - 42 = 42 + 9b - 42 \). Simplifying both sides, we have \( 0 = 9b \).

Step2: Divide by 9

Next, we divide both sides of the equation \( 0 = 9b \) by 9. So, \( \frac{0}{9} = \frac{9b}{9} \), which simplifies to \( 0 = b \).

Answer:

\( b = 0 \)
