Whakaoti i te 7(2-28+7/-7-n)=-10

$$7 ( 2 - \frac { 28 + 7 } { - 7 } - n ) = - 10$$

Whakaoti mō n

$$n = \frac{59}{7} = 8\frac{3}{7} \approx 8.428571429$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 7.

$$2-\frac{28+7}{-7}-n=-\frac{10}{7}$$

Me whakarea ngā taha e rua o te whārite ki te 7, arā, te tauraro pātahi he tino iti rawa te kitea o -7,7.

$$14+28+7-7n=-10$$

Tāpirihia te 14 ki te 28, ka 42.

$$42+7-7n=-10$$

Tāpirihia te 42 ki te 7, ka 49.

$$49-7n=-10$$

Tangohia te 49 mai i ngā taha e rua.

$$-7n=-10-49$$

Tangohia te 49 i te -10, ka -59.

$$-7n=-59$$

Whakawehea ngā taha e rua ki te -7.

$$n=\frac{-59}{-7}$$

Ka taea te hautanga \frac{-59}{-7} te whakamāmā ki te \frac{59}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$n=\frac{59}{7}$$
