Whakaoti i te .360=12+x/60+x

$$.360 = \frac { 12 + x } { 60 + x }$$

Whakaoti mō x

$$x=15$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -60 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+60.

$$0.36\left(x+60\right)=12+x$$

Whakamahia te āhuatanga tohatoha hei whakarea te 0.36 ki te x+60.

$$0.36x+21.6=12+x$$

Tangohia te x mai i ngā taha e rua.

$$0.36x+21.6-x=12$$

Pahekotia te 0.36x me -x, ka -0.64x.

$$-0.64x+21.6=12$$

Tangohia te 21.6 mai i ngā taha e rua.

$$-0.64x=12-21.6$$

Tangohia te 21.6 i te 12, ka -9.6.

$$-0.64x=-9.6$$

Whakawehea ngā taha e rua ki te -0.64.

$$x=\frac{-9.6}{-0.64}$$

Whakarohaina te \frac{-9.6}{-0.64} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-960}{-64}$$

Whakawehea te -960 ki te -64, kia riro ko 15.

$$x=15$$
