Whakaoti i te {l}{z_{1}+frac{v_{1}*v_{2}}{2}=z_{2}+frac{v_{2}}{2}}{v_{1}=3}{z_{1}=5}{z_{2}=10}

$$\left. \begin{array} { l } { z _ { 1 } + \frac { v _ { 1 } \cdot v _ { 2 } } { 2 } = z _ { 2 } + \frac { v _ { 2 } } { 2 } } \\ { v _ { 1 } = 3 } \\ { z _ { 1 } = 5 } \\ { z _ { 2 } = 10 } \end{array} \right.$$

Whakaoti mō z_1, v_1, v_2, z_2

$$z_{1}=5$$

$$v_{1}=3$$

$$v_{2}=5$$

$$z_{2}=10$$

Ngā Upane Otinga

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

$$5+\frac{3v_{2}}{2}=10+\frac{v_{2}}{2}$$

Whakareatia ngā taha e rua o te whārite ki te 2.

$$10+3v_{2}=20+v_{2}$$

Tangohia te v_{2} mai i ngā taha e rua.

$$10+3v_{2}-v_{2}=20$$

Pahekotia te 3v_{2} me -v_{2}, ka 2v_{2}.

$$10+2v_{2}=20$$

Tangohia te 10 mai i ngā taha e rua.

$$2v_{2}=20-10$$

Tangohia te 10 i te 20, ka 10.

$$2v_{2}=10$$

Whakawehea ngā taha e rua ki te 2.

$$v_{2}=\frac{10}{2}$$

Whakawehea te 10 ki te 2, kia riro ko 5.

$$v_{2}=5$$

Kua oti te pūnaha te whakatau.

$$z_{1}=5 v_{1}=3 v_{2}=5 z_{2}=10$$
