    Hi

    Just wanted to verify does:

    X4 </= 0.1X1 + 0.1X2 + 0.1X3 equal 0.1X1 + 0.1X2 + 0.1X3 – X4 >/= 0?

    If </= mean greater than or equal to then (by simple algebra):

    X4 – X4 </= 0.1X1 + 0.1X2 + 0.1X3 –X4

    0 </= 0.1X1 + 0.1X2 + 0.1X3 – X4

    or

    0.1X1 + 0.1X2 + 0.1X3 – X4 >/= 0

    Yes,Mr. Engineer, you got it right. You can add at both sides of the inequality. The only thing you gotta emeber is that if you multiply both sides of the inequality by a negative number then the sign of the inequality (less than or greater than ) changes. Everything else is handled like a normal algebraic equation.
