Whakaoti i te x-4/7+1/7=-x/14

$$\frac{ x-4 }{ 7 } + \frac{ 1 }{ 7 } = - \frac{ x }{ 14 }$$

Whakaoti mō x

$$x=2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 14, arā, te tauraro pātahi he tino iti rawa te kitea o 7,14.

$$2\left(x-4\right)+2=-x$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-4.

$$2x-8+2=-x$$

Tāpirihia te -8 ki te 2, ka -6.

$$2x-6=-x$$

Me tāpiri te x ki ngā taha e rua.

$$2x-6+x=0$$

Pahekotia te 2x me x, ka 3x.

$$3x-6=0$$

Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$3x=6$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{6}{3}$$

Whakawehea te 6 ki te 3, kia riro ko 2.

$$x=2$$
