Line 146: </math> Choose {{math\|''q'' {{=}} 3}} as the entering index. Then {{math\|'''''d''''' {{=}} [1&ensp;3]<sup>T</sup>}}, which means a unit increase in {{math\|''x''<sub>3</sub>}} ~~will~~ results in {{math\|''x''<sub>4</sub>}} and {{math\|''x''<sub>5</sub>}} being decreased by {{math\|1}} and {{math\|3}}, respectively. Therefore, {{math\|''x''<sub>3</sub>}} is increased to {{math\|5}}, at which point {{math\|''x''<sub>5</sub>}} is reduced to zero, and {{math\|''p'' {{=}} 5}} becomes the leaving index. After the pivot operation,
