Final answer:

To solve the inequality system, the first inequality 3x - 4 < 8 simplifies to x < 4, and the second inequality 2x + 2 > 4 simplifies to x > 1. The common solution for the system is the range of values where x is greater than 1 and less than 4, expressed as 1 < x < 4.

Step-by-step explanation:

To solve the inequality system, we have two inequalities to solve separately. The first inequality is 3x - 4 < 8 and the second is 2x + 2 > 4. Let's solve each step by step.

Solving the first inequality

Add 4 to both sides of the inequality 3x - 4 < 8:

3x - 4 + 4 < 8 + 4

3x < 12

Now, divide both sides by 3 to isolate x:

3x / 3 < 12 / 3

x < 4

Solving the second inequality

Subtract 2 from both sides of the inequality 2x + 2 > 4:

2x + 2 - 2 > 4 - 2

2x > 2

Then, divide both sides by 2 to isolate x:

2x / 2 > 2 / 2

x > 1

To find the solution to the system, we need the range of x that satisfies both inequalities, which is 1 < x < 4. This means that x must be greater than 1 and less than 4.
