For what values of a is the value of the binomial 2a-1 smaller than the value of the binomial 7-1.2a?

To solve the problem shown bove you must apply the proccedure shown below:

1. You have that:

2a-1< 7-1.2a

2a+1.2a<7+1

3.2a<8

a<8/3.2

a<2.5

2. Therefore, f or what values of a is the value of the binomial 2a-1 smaller than the value of the binomial 7-1.2a?

As you can see above, the answer for this question is:

All the values of a between - ∞ and 2.5
