Answer:

Let's solve this inequality step by step:

4x + 4x > -2x + 34

Simplifying the left-hand side:

8x > -2x + 34

Adding 2x to both sides:

10x > 34

Dividing by 10:

x > 3.4

Now let's solve the second inequality:

3(4x + 4) - 9 > 15x + 15

Distributing the 3:

12x + 12 - 9 > 15x + 15

Simplifying:

12x + 3 > 15x + 15

Subtracting 12x from both sides:

3 > 3x + 15

Subtracting 15 from both sides:

-12 > 3x

Dividing by 3 (and flipping the inequality sign, since we are dividing by a negative number):

x < -4

Therefore, the solution to the system of inequalities is:

x < -4 or x > 3.4.
