Whakaoti i te 0-7y/3=-4+2y/-2

$$\frac{ 0-7y }{ 3 } = - \frac{ 4+2y }{ -2 }$$

Whakaoti mō y

$$y=-\frac{3}{5}=-0.6$$

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 3,-2.

$$2\left(0-7y\right)=3\left(4+2y\right)$$

Ko te tau i tāpiria he kore ka hua koia tonu.

$$2\left(-7\right)y=3\left(4+2y\right)$$

Whakareatia te 2 ki te -7, ka -14.

$$-14y=3\left(4+2y\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4+2y.

$$-14y=12+6y$$

Tangohia te 6y mai i ngā taha e rua.

$$-14y-6y=12$$

Pahekotia te -14y me -6y, ka -20y.

$$-20y=12$$

Whakawehea ngā taha e rua ki te -20.

$$y=\frac{12}{-20}$$

Whakahekea te hautanga \frac{12}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$y=-\frac{3}{5}$$
