-22y-68\geq 52-52y
Whakamahia te āhuatanga tohatoha hei whakarea te 52 ki te 1-y.
-22y-68+52y\geq 52
Me tāpiri te 52y ki ngā taha e rua.
30y-68\geq 52
Pahekotia te -22y me 52y, ka 30y.
30y\geq 52+68
Me tāpiri te 68 ki ngā taha e rua.
30y\geq 120
Tāpirihia te 52 ki te 68, ka 120.
y\geq \frac{120}{30}
Whakawehea ngā taha e rua ki te 30. I te mea he tōrunga te 30, kāore e huri te ahunga koreōrite.
y\geq 4
Whakawehea te 120 ki te 30, kia riro ko 4.
