Whakaoti i te 3(2+y)-2(3-y)leqy

$$3 ( 2 + y ) - 2 ( 3 - y ) \leq y$$

Whakaoti mō y

$$y\leq 0$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2+y.

$$6+3y-2\left(3-y\right)\leq y$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3-y.

$$6+3y-6+2y\leq y$$

Tangohia te 6 i te 6, ka 0.

$$3y+2y\leq y$$

Pahekotia te 3y me 2y, ka 5y.

$$5y\leq y$$

Tangohia te y mai i ngā taha e rua.

$$5y-y\leq 0$$

Pahekotia te 5y me -y, ka 4y.

$$4y\leq 0$$

Ko te otinga o ngā tau e rua ko ≤0 ina ko ≥0 tētahi, ā, ko ≤0 tētahi. Ina ko 4\geq 0, ko ≤0 rawa a y.

$$y\leq 0$$
