Exercise 5 Page 385

Substitute 3 into the given inequality and then simplify.

No, see solution.

Practice makes perfect

We can determine whether 3 is a solution by substituting it into the inequality and simplifying.

b+4 < 6
Substitute

b= 3

3 + 4 ? < 6
AddTerms

Add terms

7 < 6 *

Since 7 is not less than 6, we got a false statement. This means that b=3 is not a solution of the inequality.
