Question

What is the solution set for this inequality?

−9x+18<−27


x<−1

x>−1

x<5

x>5

Answer 1

Explanation:

• -9x+18<-27

Subtracting 18 from both sides, we get

• -9x+18-18<-27-18
• -9x<-45

Dividing both sides by -9, we get

• -9x/-9>-45/-9
• x>5

Hence, option d is the correct answer.

Answer 2

Explanation:

• -9x+18<-27
• -9x+18-18<-27-18
• -9x<-45
• x>-45/-9
• x>5
