Whakaoti i te 96-2(45y+3)=12(2y-3)+3y

$$96 - 2 ( 45 y + 3 ) = 12 ( 2 y - 3 ) + 3 y$$

Whakaoti mō y

$$y = \frac{14}{13} = 1\frac{1}{13} \approx 1.076923077$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 45y+3.

$$96-90y-6=12\left(2y-3\right)+3y$$

Tangohia te 6 i te 96, ka 90.

$$90-90y=12\left(2y-3\right)+3y$$

Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te 2y-3.

$$90-90y=24y-36+3y$$

Pahekotia te 24y me 3y, ka 27y.

$$90-90y=27y-36$$

Tangohia te 27y mai i ngā taha e rua.

$$90-90y-27y=-36$$

Pahekotia te -90y me -27y, ka -117y.

$$90-117y=-36$$

Tangohia te 90 mai i ngā taha e rua.

$$-117y=-36-90$$

Tangohia te 90 i te -36, ka -126.

$$-117y=-126$$

Whakawehea ngā taha e rua ki te -117.

$$y=\frac{-126}{-117}$$

Whakahekea te hautanga \frac{-126}{-117} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -9.

$$y=\frac{14}{13}$$
