Answer 2

It looks like you have two inequalities, and you'd like to solve for the values of x that satisfy them. Let's work on each inequality separately:

1. 20x - 7 < 22x - 9 To solve this inequality, we want to isolate x on one side of the inequality sign. Start by moving the terms with x to one side and the constants to the other side:

20x - 22x < -9 + 7

Now, combine like terms:

-2x < -2

Next, divide both sides by -2, remembering to reverse the inequality sign when dividing by a negative number:

x > 1

So, the solution for the first inequality is x > 1.

2. 2x + 1 < 7.9x + 3.1 Similarly, we want to isolate x on one side of the inequality sign:

2x - 7.9x < 3.1 - 1

Combine like terms:

-5.9x < 2.1

Now, divide both sides by -5.9:

x > 2.1 / (-5.9)

x > -0.3559 (rounded to four decimal places)

So, the solution for the second inequality is x > -0.3559.

To summarize:

1. x > 1
2. x > -0.3559

These are the values of x that satisfy the given inequalities.
