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

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

Whakaoti mō x, y, z, a, b, c

$$c=4$$

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.

$$x=4 y=4 z=4 a=4 b=4 c=4$$
