Answer 2

To solve the inequalities, let's start with the first one:

2 - 3x < 4x - 12

Let's simplify the inequality:

Add 3x to both sides:

2 - 3x + 3x < 4x - 12 + 3x

2 < 7x - 12

Now, add 12 to both sides:

2 + 12 < 7x - 12 + 12

14 < 7x

Finally, divide both sides by 7:

14/7 < 7x/7

2 < x

So the solution to the first inequality is x > 2.

Now, let's move on to the second inequality:

16 + 2x > 4x + 7

Let's simplify the inequality:

Subtract 2x from both sides:

16 + 2x - 2x > 4x - 2x + 7

16 > 2x + 7

Next, subtract 7 from both sides:

16 - 7 > 2x + 7 - 7

9 > 2x

Finally, divide both sides by 2:

9/2 > 2x/2

4.5 > x

So the solution to the second inequality is x < 4.5.

Therefore, the combined solution for both inequalities is x > 2 and x < 4.5.
