If you have a constraint f ( x) ≤ b with x variables and b a constant, then you replace it with f ( x) + λ = b and λ ≥ 0 which amounts to the same thing. λ is a new variable called a slack variable (cause it "picks up the slack" of the original inequality).

WebbSimilar to slack variable, to convert an inequality to equality, we subtract a variable from the left side of a greater than or equal to constraint This is done to reduce/remove the excess on the left side For instance, X + 3Y >= 20 To convert this inequality into an equality, we subtract a surplus variable “s” from the L.H.S.
