12-3b<9
12-3b<9
-3b < -3
b < 1
3b - 12 <_ -9
To solve the inequality 12 - 3b < 9, you can follow these steps:
1. Start by isolating the variable term, which is the term that contains the variable (b). In this case, the variable term is -3b.
12 - 3b < 9
2. To isolate -3b, subtract 12 from both sides of the inequality:
12 - 3b - 12 < 9 - 12
Simplify the equation:
-3b < -3
3. Next, divide both sides of the inequality by -3. Note that when you divide by a negative number, the inequality flips.
-3b / -3 > -3 / -3
Simplify the equation:
b > 1
So the solution to the inequality 12 - 3b < 9 is b > 1.
