Need help solving this problem 12-3b <9

Answers

Answer 1

Answer:

The solution of the inequality, 12 - 3b < 9 is 1 < b.

How to solve inequalities?

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Therefore, let's solve the inequalities for the variable b. A variable is a number represented by a letter in an equation or inequality.

Hence,

12 - 3b < 9

subtract 9 from both sides of the inequality

12 - 9 - 3b < 9 - 9

3 - 3b < 0

add 3b to both sides of the inequality

3 - 3b < 0

3 - 3b + 3b < 0 + 3b

3 < 3b

divide both sides by 3

1 < b
