Whakaoti i te mn/4+4(m+1)0.075=68

$$\frac { m n } { 4 } + 4 ( m + 1 ) 0.075 = 68$$

Whakaoti mō m

$$m=\frac{1354}{5\left(n+1.2\right)}$$

$$n\neq -\frac{6}{5}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 4.

$$mn+16\left(m+1\right)\times 0.075=272$$

Whakareatia te 16 ki te 0.075, ka 1.2.

$$mn+1.2\left(m+1\right)=272$$

Whakamahia te āhuatanga tohatoha hei whakarea te 1.2 ki te m+1.

$$mn+1.2m+1.2=272$$

Tangohia te 1.2 mai i ngā taha e rua.

$$mn+1.2m=272-1.2$$

Tangohia te 1.2 i te 272, ka 270.8.

$$mn+1.2m=270.8$$

Pahekotia ngā kīanga tau katoa e whai ana i te m.

$$\left(n+1.2\right)m=270.8$$

Whakawehea ngā taha e rua ki te n+1.2.

$$\frac{\left(n+1.2\right)m}{n+1.2}=\frac{270.8}{n+1.2}$$

Mā te whakawehe ki te n+1.2 ka wetekia te whakareanga ki te n+1.2.

$$m=\frac{270.8}{n+1.2}$$

Whakawehe 270.8 ki te n+1.2.

$$m=\frac{1354}{5\left(n+1.2\right)}$$

Whakaoti mō n

$$n=-1.2+\frac{1354}{5m}$$

$$m\neq 0$$

Whakareatia te 16 ki te 0.075, ka 1.2.

$$mn+1.2\left(m+1\right)=272$$

Whakamahia te āhuatanga tohatoha hei whakarea te 1.2 ki te m+1.

$$mn+1.2m+1.2=272$$

Tangohia te 1.2m mai i ngā taha e rua.

$$mn+1.2=272-1.2m$$

Tangohia te 1.2 mai i ngā taha e rua.

$$mn=272-1.2m-1.2$$

Tangohia te 1.2 i te 272, ka 270.8.

$$mn=270.8-1.2m$$

He hanga arowhānui tō te whārite.

$$mn=\frac{1354-6m}{5}$$

Whakawehea ngā taha e rua ki te m.

$$\frac{mn}{m}=\frac{1354-6m}{5m}$$

Mā te whakawehe ki te m ka wetekia te whakareanga ki te m.

$$n=\frac{1354-6m}{5m}$$

Whakawehe \frac{1354-6m}{5} ki te m.

$$n=-\frac{6}{5}+\frac{1354}{5m}$$
