Whakaoti i te -14x+13leq-13(x-1)

$$- 14 x + 13 \leq - 13 ( x - 1 )$$

Whakaoti mō x

$$x\geq 0$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -13 ki te x-1.

$$-14x+13\leq -13x+13$$

Me tāpiri te 13x ki ngā taha e rua.

$$-14x+13+13x\leq 13$$

Pahekotia te -14x me 13x, ka -x.

$$-x+13\leq 13$$

Tangohia te 13 mai i ngā taha e rua.

$$-x\leq 13-13$$

Tangohia te 13 i te 13, ka 0.

$$-x\leq 0$$

Ko te otinga o ngā tau e rua ko ≤0 ina ko ≥0 tētahi, ā, ko ≤0 tētahi. Ina ko -1\leq 0, ko ≥0 rawa a x.

$$x\geq 0$$
