Kua tāruatia ki te papatopenga
4\left(a-4\right)\geq 3\left(2a+2\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4. I te mea he tōrunga te 12, kāore e huri te ahunga koreōrite.
4a-16\geq 3\left(2a+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te a-4.
4a-16\geq 6a+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2a+2.
4a-16-6a\geq 6
Tangohia te 6a mai i ngā taha e rua.
-2a-16\geq 6
Pahekotia te 4a me -6a, ka -2a.
-2a\geq 6+16
Me tāpiri te 16 ki ngā taha e rua.
-2a\geq 22
Tāpirihia te 6 ki te 16, ka 22.
a\leq \frac{22}{-2}
Whakawehea ngā taha e rua ki te -2. I te mea he tōraro a -2, ka huri te ahunga koreōrite.
a\leq -11
Whakawehea te 22 ki te -2, kia riro ko -11.
