Whakaoti i te 2.3*22+(2.3+1.1)*(0.7m-22)=71

$$2.3 \times 22 + ( 2.3 + 1.1 ) \times ( 0.7 m - 22 ) = 71$$

Whakaoti mō m

$$m=40$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 2.3 ki te 22, ka 50.6.

$$50.6+\left(2.3+1.1\right)\left(0.7m-22\right)=71$$

Tāpirihia te 2.3 ki te 1.1, ka 3.4.

$$50.6+3.4\left(0.7m-22\right)=71$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3.4 ki te 0.7m-22.

$$50.6+2.38m-74.8=71$$

Tangohia te 74.8 i te 50.6, ka -24.2.

$$-24.2+2.38m=71$$

Me tāpiri te 24.2 ki ngā taha e rua.

$$2.38m=71+24.2$$

Tāpirihia te 71 ki te 24.2, ka 95.2.

$$2.38m=95.2$$

Whakawehea ngā taha e rua ki te 2.38.

$$m=\frac{95.2}{2.38}$$

Whakarohaina te \frac{95.2}{2.38} mā te whakarea i te taurunga me te tauraro ki te 100.

$$m=\frac{9520}{238}$$

Whakawehea te 9520 ki te 238, kia riro ko 40.

$$m=40$$
