Whakaoti i te 5(1/2x-5)=2

$$5 ( \frac { 1 } { 2 } x - 5 ) = 2$$

Whakaoti mō x

$$x = \frac{54}{5} = 10\frac{4}{5} = 10.8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 5.

$$\frac{1}{2}x-5=\frac{2}{5}$$

Me tāpiri te 5 ki ngā taha e rua.

$$\frac{1}{2}x=\frac{2}{5}+5$$

Me tahuri te 5 ki te hautau \frac{25}{5}.

$$\frac{1}{2}x=\frac{2}{5}+\frac{25}{5}$$

Tā te mea he rite te tauraro o \frac{2}{5} me \frac{25}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1}{2}x=\frac{2+25}{5}$$

Tāpirihia te 2 ki te 25, ka 27.

$$\frac{1}{2}x=\frac{27}{5}$$

Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.

$$x=\frac{27}{5}\times 2$$

Tuhia te \frac{27}{5}\times 2 hei hautanga kotahi.

$$x=\frac{27\times 2}{5}$$

Whakareatia te 27 ki te 2, ka 54.

$$x=\frac{54}{5}$$
