Whakaoti i te {l}{2x+1=3}{2y+2=4}

$$\left. \begin{array} { l } { 2 x + 1 = 3 } \\ { 2 y + 2 = 4 } \end{array} \right.$$

Whakaoti mō x, y

$$x=1$$

$$y=1$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 1 mai i ngā taha e rua.

$$2x=3-1$$

Tangohia te 1 i te 3, 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.

$$x=1$$

Whakaarohia te whārite tuarua. Tangohia te 2 mai i ngā taha e rua.

$$2y=4-2$$

Tangohia te 2 i te 4, ka 2.

$$2y=2$$

Whakawehea ngā taha e rua ki te 2.

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

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

$$y=1$$

Kua oti te pūnaha te whakatau.

$$x=1 y=1$$
