Equation with the variable in the denominator. Figuring out missing algebraic step. Nettetaffected by changes in the value of a nonbasic variable. Furthermore, since the basic variables must remain non-negative the solution must satisfy X Bi* = (B-1b) i* - (B-1a ) i* X = 0 This equation permits the derivation of a bound on the maximum amount the nonbasic variable X can be changed while the basic variables remain non-negative.
