Whakaoti i te {l}{82=2(-5m+1)}{-2(1+8r)=94}

$$\left. \begin{array} { l } { 82 = 2 ( - 5 m + 1 ) } \\ { - 2 ( 1 + 8 r ) = 94 } \end{array} \right.$$

Whakaoti mō m, r

$$r=-6$$

$$m=-8$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 2.

$$\frac{82}{2}=-5m+1$$

Whakawehea te 82 ki te 2, kia riro ko 41.

$$41=-5m+1$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$-5m+1=41$$

Tangohia te 1 mai i ngā taha e rua.

$$-5m=41-1$$

Tangohia te 1 i te 41, ka 40.

$$-5m=40$$

Whakawehea ngā taha e rua ki te -5.

$$m=\frac{40}{-5}$$

Whakawehea te 40 ki te -5, kia riro ko -8.

$$m=-8$$

Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te -2.

$$1+8r=\frac{94}{-2}$$

Whakawehea te 94 ki te -2, kia riro ko -47.

$$1+8r=-47$$

Tangohia te 1 mai i ngā taha e rua.

$$8r=-47-1$$

Tangohia te 1 i te -47, ka -48.

$$8r=-48$$

Whakawehea ngā taha e rua ki te 8.

$$r=\frac{-48}{8}$$

Whakawehea te -48 ki te 8, kia riro ko -6.

$$r=-6$$

Kua oti te pūnaha te whakatau.

$$m=-8 r=-6$$
