Question

solve for b.
8b + 9 = 7b
b = \boxed{}

Explanation:

Step1: Subtract 7b from both sides

To isolate the variable \( b \), we first subtract \( 7b \) from both sides of the equation \( 8b + 9 = 7b \). This gives us \( 8b - 7b + 9 = 7b - 7b \). Simplifying both sides, we have \( b + 9 = 0 \).

Step2: Subtract 9 from both sides

Next, we subtract 9 from both sides to solve for \( b \). So, \( b + 9 - 9 = 0 - 9 \), which simplifies to \( b = -9 \).

Answer:

\( b = -9 \)
