Question: Given the system below that was converted to equations from inequalities for the mixed constraint minimization linear programming problem with variables x, y, z, slack

Given the system below that was converted to equations from inequalities for the mixed constraint minimization linear programming problem with variables x, y, z, slack variable r, surplus variables s and t, and artificial variables a and b, find the optimal solution: 2x+3y+4z+1r = 14 3x+1y+5z-1s+a= 4 1x+4y+ 3z -1t+b= 6 4x + 2y +1z + 1P= 0
