Whakaoti i te 1/5x+2=3/7x

$$\frac{ 1 }{ 5 } x+2= \frac{ 3 }{ 7 } x$$

Whakaoti mō x

$$x = \frac{35}{4} = 8\frac{3}{4} = 8.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{3}{7}x mai i ngā taha e rua.

$$\frac{1}{5}x+2-\frac{3}{7}x=0$$

Pahekotia te \frac{1}{5}x me -\frac{3}{7}x, ka -\frac{8}{35}x.

$$-\frac{8}{35}x+2=0$$

Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-\frac{8}{35}x=-2$$

Me whakarea ngā taha e rua ki te -\frac{35}{8}, te tau utu o -\frac{8}{35}.

$$x=-2\left(-\frac{35}{8}\right)$$

Tuhia te -2\left(-\frac{35}{8}\right) hei hautanga kotahi.

$$x=\frac{-2\left(-35\right)}{8}$$

Whakareatia te -2 ki te -35, ka 70.

$$x=\frac{70}{8}$$

Whakahekea te hautanga \frac{70}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{35}{4}$$
