Whakaoti i te -3y-2/2=-12y+1/-6

$$\frac { - 3 y - 2 } { 2 } = \frac { - 12 y + 1 } { - 6 }$$

Whakaoti mō y

$$y=-\frac{5}{21}\approx -0.238095238$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,-6.

$$3\left(-3y-2\right)=-\left(-12y+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -3y-2.

$$-9y-6=-\left(-12y+1\right)$$

Hei kimi i te tauaro o -12y+1, kimihia te tauaro o ia taurangi.

$$-9y-6=-\left(-12y\right)-1$$

Ko te tauaro o -12y ko 12y.

$$-9y-6=12y-1$$

Tangohia te 12y mai i ngā taha e rua.

$$-9y-6-12y=-1$$

Pahekotia te -9y me -12y, ka -21y.

$$-21y-6=-1$$

Me tāpiri te 6 ki ngā taha e rua.

$$-21y=-1+6$$

Tāpirihia te -1 ki te 6, ka 5.

$$-21y=5$$

Whakawehea ngā taha e rua ki te -21.

$$y=\frac{5}{-21}$$

Ka taea te hautanga \frac{5}{-21} te tuhi anō ko -\frac{5}{21} mā te tango i te tohu tōraro.

$$y=-\frac{5}{21}$$
