Whakaoti i te 6+3(1+3x)=2x

$$6+3(1+3x)=2x$$

Whakaoti mō x

$$x = -\frac{9}{7} = -1\frac{2}{7} \approx -1.285714286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 1+3x.

$$6+3+9x=2x$$

Tāpirihia te 6 ki te 3, ka 9.

$$9+9x=2x$$

Tangohia te 2x mai i ngā taha e rua.

$$9+9x-2x=0$$

Pahekotia te 9x me -2x, ka 7x.

$$9+7x=0$$

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

$$7x=-9$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{-9}{7}$$

Ka taea te hautanga \frac{-9}{7} te tuhi anō ko -\frac{9}{7} mā te tango i te tohu tōraro.

$$x=-\frac{9}{7}$$
