Question

Find all possible values of each expression if you know that 3 < a < 4--> -a

Answer 1

All the possible values of a must be less than 3.75 excluding values from 3 and below

Inequalities are expressions that are not separated by an equal sign

Since we are not given the required inequality expression, Let us assume the equation below:

10 - 5a > -a

Add 5a to both sides

15 - 5a + 5a > -a + 5a

15 > 4a

4a<15

a < 15/4

a<3.75

Since the value of a is less than 3.75, hence all the possible values of a must be less than 3.75 excluding values from 3 and below.

NB: The inequality expression was assumed, the same concept can be applied to any other expression
