Whakaoti i te {l}{{(x+1)}-{(x-1)}=3-x+3}{y=4}{text{Solvefor}ztext{where}}{z=y}

$$\left. \begin{array} { l } { {(x + 1)} - {(x - 1)} = 3 - x + 3 }\\ { y = 4 }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Whakaoti mō x, y, z

$$z=4$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Hei kimi i te tauaro o x-1, kimihia te tauaro o ia taurangi.

$$x+1-x+1=3-x+3$$

Pahekotia te x me -x, ka 0.

$$1+1=3-x+3$$

Tāpirihia te 1 ki te 1, ka 2.

$$2=3-x+3$$

Tāpirihia te 3 ki te 3, ka 6.

$$2=6-x$$

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

$$6-x=2$$

Tangohia te 6 mai i ngā taha e rua.

$$-x=2-6$$

Tangohia te 6 i te 2, ka -4.

$$-x=-4$$

Whakawehea ngā taha e rua ki te -1.

$$x=\frac{-4}{-1}$$

Ka taea te hautanga \frac{-4}{-1} te whakamāmā ki te 4 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=4$$

Kua oti te pūnaha te whakatau.

$$x=4 y=4 z=4$$
