Whakaoti i te 2/7x+1/7=-3/7

$$\frac { 2 } { 7 } x + \frac { 1 } { 7 } = - \frac { 3 } { 7 }$$

Whakaoti mō x

$$x=-2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{7} mai i ngā taha e rua.

$$\frac{2}{7}x=-\frac{3}{7}-\frac{1}{7}$$

Tā te mea he rite te tauraro o -\frac{3}{7} me \frac{1}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2}{7}x=\frac{-3-1}{7}$$

Tangohia te 1 i te -3, ka -4.

$$\frac{2}{7}x=-\frac{4}{7}$$

Me whakarea ngā taha e rua ki te \frac{7}{2}, te tau utu o \frac{2}{7}.

$$x=-\frac{4}{7}\times \frac{7}{2}$$

Me whakarea te -\frac{4}{7} ki te \frac{7}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{-4\times 7}{7\times 2}$$

Me whakakore tahi te 7 i te taurunga me te tauraro.

$$x=\frac{-4}{2}$$

Whakawehea te -4 ki te 2, kia riro ko -2.

$$x=-2$$
