Whakaoti i te 112left(5y-1right)+3left(134-7yright)=36

$$112 \left( 5y-1 \right) +3 \left( 134-7y \right) = 36$$

Whakaoti mō y

$$y=-\frac{254}{539}\approx -0.471243043$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 112 ki te 5y-1.

$$560y-112+3\left(134-7y\right)=36$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 134-7y.

$$560y-112+402-21y=36$$

Tāpirihia te -112 ki te 402, ka 290.

$$560y+290-21y=36$$

Pahekotia te 560y me -21y, ka 539y.

$$539y+290=36$$

Tangohia te 290 mai i ngā taha e rua.

$$539y=36-290$$

Tangohia te 290 i te 36, ka -254.

$$539y=-254$$

Whakawehea ngā taha e rua ki te 539.

$$y=\frac{-254}{539}$$

Ka taea te hautanga \frac{-254}{539} te tuhi anō ko -\frac{254}{539} mā te tango i te tohu tōraro.

$$y=-\frac{254}{539}$$
