Answer:
x < 9
Explanation:
Notice that the sign here is <, not =.
This is an inequality, not an equation.
When you solve an equation, you typically get an answer that x equals a certain number. When you solve an inequality, you typically get an answer that x is greater than a number or x is less than a number, so there are many numbers that are solutions to an inequality.
Let's solve this inequality.
2x + 9 < 27
Subtract 9 from both sides.
2x < 18
Divide both sides by 2.
x < 9
Answer: x < 9
Every number less than 9 is a solution to this inequality.
