$$11.2 \left( 5y-1 \right) +3 \left( 13.4-7y \right) = 36$$

Whakaoti mō y

$$y=0.2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 11.2 ki te 5y-1.

$$56y-11.2+3\left(13.4-7y\right)=36$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 13.4-7y.

$$56y-11.2+40.2-21y=36$$

Tāpirihia te -11.2 ki te 40.2, ka 29.

$$56y+29-21y=36$$

Pahekotia te 56y me -21y, ka 35y.

$$35y+29=36$$

Tangohia te 29 mai i ngā taha e rua.

$$35y=36-29$$

Tangohia te 29 i te 36, ka 7.

$$35y=7$$

Whakawehea ngā taha e rua ki te 35.

$$y=\frac{7}{35}$$

Whakahekea te hautanga \frac{7}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$y=\frac{1}{5}$$
