two less than a number is less than 9

Question

writing and sloving inequalities by using addition or subtraction

Answer 1

Let x = a number

 

 

We set up an inequality

 

x - 2 < 9

 

We solve an inequality the same way we solve equations.

 

x < 9 + 2

x < 11

 

Any number less than 11 not including 11 will make this statement true.
