Solve for b. 8b + 9 = 7b b = ____

Start Equation Isolation: Start with the equation 8b + 9 = 7b. To isolate the variable b, we need to get all the b terms on one side of the equation. Subtract 7b from both sides of the equation to move the b terms to one side. 8b + 9 - 7b = 7b - 7bCombine Like Terms: Simplify both sides of the equation. On the left side, combine like terms (8b - 7b). On the right side, 7b - 7b cancels out to 0. 8b - 7b + 9 = 0 b + 9 = 0Subtract to Solve for b: Subtract 9 from both sides to solve for b. b + 9 - 9 = 0 - 9 b = -9

b =

____

Start Equation Isolation: Start with the equation $8b + 9 = 7b$ . To isolate the variable $b$ , we need to get all the $b$ terms on one side of the equation. Subtract $7b$ from both sides of the equation to move the $b$ terms to one side. $8b + 9 - 7b = 7b - 7b$
Combine Like Terms: Simplify both sides of the equation. $\newline$ On the left side, combine like terms $8b - 7b$ . $\newline$ On the right side, $7b - 7b$ cancels out to $0$ . $\newline$ $8b - 7b + 9 = 0$ $\newline$ $b + 9 = 0$
Subtract to Solve for b: Subtract $9$ from both sides to solve for $b$ . $\newline$ $b + 9 - 9 = 0 - 9$ $\newline$ $b = -9$
