Let's consider the following LP.
$$ \max z = 2x_1 + 3x_2 + x_3 $$
$$ \text{s.t. } \begin{align} \\ \\ \\ & 3x_1 + 2x_2 + 4x3 \le 7 \\ & 5x_1 -2x_3 \ge 1 \\ & x_1 + 2x_2 + x_3 = 2 \\ & x_1, x_2, x_3 \ge 0 \end{align} $$
a) Prepare Excel spreadsheets to apply the Affine Scaling Approach to solve it. Suppose x^(0)=[0.5,0.5,0.5]^T and consider as 0.8.
b) Solve this problem by using a classical solver such as Excel solver, Gams or Lindo and compare your results with the results in part (a).
Actually i could not use alpha on the problem, Could someone please help? Screenshot of the question
After substituting the equality the problem reads
$$ \max z = x_1+x_2 + 2 $$
s.t
$$ x_1+6x_2 \ge 1\\ 7x_1+4x_2 \ge 5\\ x_1 \ge 0\\ x_2 \ge 0\\ x_1+2x_2 \le 2 $$
