Linear Programming LPP Simplex Method

$z = 6x_1 + 12x_2$

$z = 15x_1 + 21x_2$

$z = 12x_1 + 4x_2$

$z = 21x_1 + 15x_2$ (correct)

$x_1 - 2x_2 ext{ } ext{ is less than } -6$

$x_1 - 2x_2 ightarrow -6$ (correct)

$4x_1 + 3x_2 = 12$

$4x_1 + 3x_2 ightarrow 12$

All values of $x_1$ and $x_2$ equal to the line $4x_1 + 3x_2 = 12$

All values of $x_1$ and $x_2$ above the line $4x_1 + 3x_2 = 12$

Any negative values of $x_1$ and $x_2$

All values of $x_1$ and $x_2$ below the line $4x_1 + 3x_2 = 12$ (correct)
