Whakaoti i te 2x+13=1/3x-7

$$2x+13 = \frac{ 1 }{ 3 } x-7$$

Whakaoti mō x

$$x=-12$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{3}x mai i ngā taha e rua.

$$2x+13-\frac{1}{3}x=-7$$

Pahekotia te 2x me -\frac{1}{3}x, ka \frac{5}{3}x.

$$\frac{5}{3}x+13=-7$$

Tangohia te 13 mai i ngā taha e rua.

$$\frac{5}{3}x=-7-13$$

Tangohia te 13 i te -7, ka -20.

$$\frac{5}{3}x=-20$$

Me whakarea ngā taha e rua ki te \frac{3}{5}, te tau utu o \frac{5}{3}.

$$x=-20\times \frac{3}{5}$$

Tuhia te -20\times \frac{3}{5} hei hautanga kotahi.

$$x=\frac{-20\times 3}{5}$$

Whakareatia te -20 ki te 3, ka -60.

$$x=\frac{-60}{5}$$

Whakawehea te -60 ki te 5, kia riro ko -12.

$$x=-12$$
