Whakaoti i te 450+(m-5)*195=(m-2)*180

$$450 + ( m - 5 ) \times 195 = ( m - 2 ) \times 180$$

Whakaoti mō m

$$m=11$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te m-5 ki te 195.

$$450+195m-975=\left(m-2\right)\times 180$$

Tangohia te 975 i te 450, ka -525.

$$-525+195m=\left(m-2\right)\times 180$$

Whakamahia te āhuatanga tohatoha hei whakarea te m-2 ki te 180.

$$-525+195m=180m-360$$

Tangohia te 180m mai i ngā taha e rua.

$$-525+195m-180m=-360$$

Pahekotia te 195m me -180m, ka 15m.

$$-525+15m=-360$$

Me tāpiri te 525 ki ngā taha e rua.

$$15m=-360+525$$

Tāpirihia te -360 ki te 525, ka 165.

$$15m=165$$

Whakawehea ngā taha e rua ki te 15.

$$m=\frac{165}{15}$$

Whakawehea te 165 ki te 15, kia riro ko 11.

$$m=11$$
