Whakaoti i te 3=17-x/1-(-3)

$$3= \frac{ 17-x }{ 1-(-3) }$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Ko te tauaro o -3 ko 3.

$$3=\frac{17-x}{1+3}$$

Tāpirihia te 1 ki te 3, ka 4.

$$3=\frac{17-x}{4}$$

Whakawehea ia wā o 17-x ki te 4, kia riro ko \frac{17}{4}-\frac{1}{4}x.

$$3=\frac{17}{4}-\frac{1}{4}x$$

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

$$\frac{17}{4}-\frac{1}{4}x=3$$

Tangohia te \frac{17}{4} mai i ngā taha e rua.

$$-\frac{1}{4}x=3-\frac{17}{4}$$

Me tahuri te 3 ki te hautau \frac{12}{4}.

$$-\frac{1}{4}x=\frac{12}{4}-\frac{17}{4}$$

Tā te mea he rite te tauraro o \frac{12}{4} me \frac{17}{4}, me tango rāua mā te tango i ō raua taurunga.

$$-\frac{1}{4}x=\frac{12-17}{4}$$

Tangohia te 17 i te 12, ka -5.

$$-\frac{1}{4}x=-\frac{5}{4}$$

Me whakarea ngā taha e rua ki te -4, te tau utu o -\frac{1}{4}.

$$x=-\frac{5}{4}\left(-4\right)$$

Tuhia te -\frac{5}{4}\left(-4\right) hei hautanga kotahi.

$$x=\frac{-5\left(-4\right)}{4}$$

Whakareatia te -5 ki te -4, ka 20.

$$x=\frac{20}{4}$$

Whakawehea te 20 ki te 4, kia riro ko 5.

$$x=5$$
