12x-20+5\leq 16x+1
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3x-5.
12x-15\leq 16x+1
Tāpirihia te -20 ki te 5, ka -15.
12x-15-16x\leq 1
Tangohia te 16x mai i ngā taha e rua.
-4x-15\leq 1
Pahekotia te 12x me -16x, ka -4x.
-4x\leq 1+15
Me tāpiri te 15 ki ngā taha e rua.
-4x\leq 16
Tāpirihia te 1 ki te 15, ka 16.
x\geq \frac{16}{-4}
Whakawehea ngā taha e rua ki te -4. Nō te mea he <0 te -4, ka hurihia te ahunga koreōrite.
x\geq -4
Whakawehea te 16 ki te -4, kia riro ko -4.
