Whakaoti i te 3+1/5x+6+1/2x=x

$$3 + \frac { 1 } { 5 } x + 6 + \frac { 1 } { 2 } x = x$$

Whakaoti mō x

$$x=30$$

Tāpirihia te 3 ki te 6, ka 9.

$$9+\frac{1}{5}x+\frac{1}{2}x=x$$

Pahekotia te \frac{1}{5}x me \frac{1}{2}x, ka \frac{7}{10}x.

$$9+\frac{7}{10}x=x$$

Tangohia te x mai i ngā taha e rua.

$$9+\frac{7}{10}x-x=0$$

Pahekotia te \frac{7}{10}x me -x, ka -\frac{3}{10}x.

$$9-\frac{3}{10}x=0$$

Tangohia te 9 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-\frac{3}{10}x=-9$$

Me whakarea ngā taha e rua ki te -\frac{10}{3}, te tau utu o -\frac{3}{10}.

$$x=-9\left(-\frac{10}{3}\right)$$

Tuhia te -9\left(-\frac{10}{3}\right) hei hautanga kotahi.

$$x=\frac{-9\left(-10\right)}{3}$$

Whakareatia te -9 ki te -10, ka 90.

$$x=\frac{90}{3}$$

Whakawehea te 90 ki te 3, kia riro ko 30.

$$x=30$$
