Whakaoti i te 3h=7(2/7-3/7h)-10

$$3 h = 7 ( \frac { 2 } { 7 } - \frac { 3 } { 7 } h ) - 10$$

Whakaoti mō h

$$h = -\frac{4}{3} = -1\frac{1}{3} \approx -1.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te \frac{2}{7}-\frac{3}{7}h.

$$3h=7\times \frac{2}{7}+7\left(-\frac{3}{7}\right)h-10$$

Me whakakore te 7 me te 7.

$$3h=2+7\left(-\frac{3}{7}\right)h-10$$

Me whakakore te 7 me te 7.

$$3h=2-3h-10$$

Tangohia te 10 i te 2, ka -8.

$$3h=-8-3h$$

Me tāpiri te 3h ki ngā taha e rua.

$$3h+3h=-8$$

Pahekotia te 3h me 3h, ka 6h.

$$6h=-8$$

Whakawehea ngā taha e rua ki te 6.

$$h=\frac{-8}{6}$$

Whakahekea te hautanga \frac{-8}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$h=-\frac{4}{3}$$
