Whakaoti i te {l}{3x-2y=3x+3}{3y+2x=3y+2}

$$\left. \begin{array} { l } { 3 x - 2 y = 3 x + 3 } \\ { 3 y + 2 x = 3 y + 2 } \end{array} \right.$$

Whakaoti mō x, y

$$x=1$$

$$y = -\frac{3}{2} = -1\frac{1}{2} = -1.5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 3x mai i ngā taha e rua.

$$3x-2y-3x=3$$

Pahekotia te 3x me -3x, ka 0.

$$-2y=3$$

Whakawehea ngā taha e rua ki te -2.

$$y=-\frac{3}{2}$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$3\left(-\frac{3}{2}\right)+2x=3\left(-\frac{3}{2}\right)+2$$

Whakareatia te 3 ki te -\frac{3}{2}, ka -\frac{9}{2}.

$$-\frac{9}{2}+2x=3\left(-\frac{3}{2}\right)+2$$

Whakareatia te 3 ki te -\frac{3}{2}, ka -\frac{9}{2}.

$$-\frac{9}{2}+2x=-\frac{9}{2}+2$$

Tāpirihia te -\frac{9}{2} ki te 2, ka -\frac{5}{2}.

$$-\frac{9}{2}+2x=-\frac{5}{2}$$

Me tāpiri te \frac{9}{2} ki ngā taha e rua.

$$2x=-\frac{5}{2}+\frac{9}{2}$$

Tāpirihia te -\frac{5}{2} ki te \frac{9}{2}, ka 2.

$$2x=2$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{2}{2}$$

Whakawehea te 2 ki te 2, kia riro ko 1.

$$x=1$$

Kua oti te pūnaha te whakatau.

$$x=1 y=-\frac{3}{2}$$
