Let's solve the given linear programming problem using the Simplex Method. The problem is:

Maximize:
$z = 5x_1 + 4x_2$

Subject to the constraints:
$4x_1 + 2x_2 \leq 10$
$3x_1 + 2x_2 \leq 9$
$8x_1 + 3x_2 \leq 12$
$x_1, x_2 \geq 0$

Step 1: Convert the inequalities into equations by introducing slack variables.

$4x_1 + 2x_2 + s_1 = 10$
$3x_1 + 2x_2 + s_2 = 9$
$8x_1 + 3x_2 + s_3 = 12$

Where $s_1, s_2, s_3 \geq 0$ are slack variables.

Now, the objective function becomes:

$z = 5x_1 + 4x_2$

Step 2: Set up the initial simplex tableau.

& x_1 & x_2 & s_1 & s_2 & s_3 & z & \text{RHS} \\ \hline \text{Constraint 1} & 4 & 2 & 1 & 0 & 0 & 0 & 10 \\ \text{Constraint 2} & 3 & 2 & 0 & 1 & 0 & 0 & 9 \\ \text{Constraint 3} & 8 & 3 & 0 & 0 & 1 & 0 & 12 \\ \hline \text{Objective} & -5 & -4 & 0 & 0 & 0 & 1 & 0 \\ \end{array}$$ ### Step 3: Apply the simplex method. 1. **Choose the entering variable**: The most negative value in the bottom row is $$-5$$ under $$x_1$$. So, $$x_1$$ is the entering variable. 2. **Choose the leaving variable**: To determine the leaving variable, divide the right-hand side values by the corresponding coefficients of $$x_1$$ in each constraint. We select the smallest positive ratio. $$\frac{10}{4} = 2.5, \quad \frac{9}{3} = 3, \quad \frac{12}{8} = 1.5$$ The smallest ratio is 1.5, so the leaving variable is $$s_3$$. Pivot on the element at the intersection of $$x_1$$ and the 3rd constraint (8). ### Step 4: Perform pivot operation. I'll calculate the updated tableau using the pivot, then proceed with further iterations. Let me calculate that now.After performing the pivot operation, the updated simplex tableau is: $$\begin{array}{c|cccccc|c} & x_1 & x_2 & s_1 & s_2 & s_3 & z & \text{RHS} \\ \hline \text{Constraint 1} & 0 & 2 & 1 & 0 & 0 & 0 & 6 \\ \text{Constraint 2} & 0 & 2 & 0 & 1 & 0 & 0 & 6 \\ \text{Constraint 3} & 1 & 0 & 0 & 0 & 0 & 0 & 1 \\ \hline \text{Objective} & 0 & -4 & 0 & 0 & 0 & 1 & 5 \\ \end{array}$$ ### Step 5: Next Iteration 1. **Choose the entering variable**: The most negative value in the bottom row is $$-4$$ under $$x_2$$. Thus, $$x_2$$ is the entering variable. 2. **Choose the leaving variable**: Now, we calculate the ratio of the right-hand side values to the coefficients of $$x_2$$ in the rows where $$x_2 > 0$$. $$\frac{6}{2} = 3, \quad \frac{6}{2} = 3$$ Both ratios are equal, so we can choose either. I'll choose the first constraint to leave, where $$s_1$$ will leave the basis. I'll perform the pivot operation for $$x_2$$.It seems like I can’t do more advanced data analysis right now.
