0.3a+50-0.5a\leq 50
Whakamahia te āhuatanga tohatoha hei whakarea te 0.5 ki te 100-a.
-0.2a+50\leq 50
Pahekotia te 0.3a me -0.5a, ka -0.2a.
-0.2a\leq 50-50
Tangohia te 50 mai i ngā taha e rua.
-0.2a\leq 0
Tangohia te 50 i te 50, ka 0.
a\geq 0
Ko te otinga o ngā tau e rua ko ≤0 ina ko ≥0 tētahi, ā, ko ≤0 tētahi. Ina ko -0.2\leq 0, ko ≥0 rawa a a.
