Given the inequalities:

1. $a < 2b - 1$
2. $b < c + 2$
3. $c < 3a - 4$

we need to find the smallest positive integer value for $a$ that satisfies all these conditions.

Let's proceed by testing small integer values of $a$ to see if we can find a feasible solution.

Step-by-Step Solution

Step 1: Assume $a = 1$

If $a = 1$, we substitute into the first inequality: $1 < 2b - 1 \Rightarrow 2 < 2b \Rightarrow b > 1$ Thus, $b$ must be at least 2 for $a = 1$.

Next, substitute $b = 2$ into the second inequality: $2 < c + 2 \Rightarrow c > 0$ Thus, $c$ must be at least 1.

Finally, substitute $a = 1$ and $c = 1$ into the third inequality: $1 < 3(1) - 4 \Rightarrow 1 < -1$ This is not possible, so $a = 1$ does not satisfy the conditions.

Step 2: Assume $a = 2$

If $a = 2$, we substitute into the first inequality: $2 < 2b - 1 \Rightarrow 3 < 2b \Rightarrow b > 1.5$ Thus, $b$ must be at least 2.

Next, substitute $b = 2$ into the second inequality: $2 < c + 2 \Rightarrow c > 0$ Thus, $c$ must be at least 1.

Finally, substitute $a = 2$ and $c = 1$ into the third inequality: $1 < 3(2) - 4 \Rightarrow 1 < 2$ This is true, so $a = 2$ satisfies all conditions.

Conclusion

The smallest positive integer value for $a$ that satisfies all the inequalities is: $\boxed{2}$

5. Could this problem be solved graphically?

Tip: When solving inequalities, break down each step carefully, as small errors can lead to incorrect conclusions.
