Whakaoti i te {l}{x^3+7=y}{z^2+4^2=x}{z=sqrt{3}}

$$\left\{ \begin{array} { l } { x ^ { 3 } + 7 = y } \\ { z ^ { 2 } + 4 ^ { 2 } = x } \\ { z = \sqrt { 3 } } \end{array} \right.$$

Whakaoti mō x, y, z

$$x=19$$

$$y=6866$$

$$z=\sqrt{3}\approx 1.732050808$$

Ngā Upane Otinga

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

$$\left(\sqrt{3}\right)^{2}+4^{2}=x$$

Ko te pūrua o \sqrt{3} ko 3.

$$3+4^{2}=x$$

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$3+16=x$$

Tāpirihia te 3 ki te 16, ka 19.

$$19=x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x=19$$

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

$$19^{3}+7=y$$

Tātaihia te 19 mā te pū o 3, kia riro ko 6859.

$$6859+7=y$$

Tāpirihia te 6859 ki te 7, ka 6866.

$$6866=y$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$y=6866$$

Kua oti te pūnaha te whakatau.

$$x=19 y=6866 z=\sqrt{3}$$
