Whakaoti i te 4-7-3x/5=3-3-7x/10-x+1/2

$$4 - \frac { 7 - 3 x } { 5 } = 3 - \frac { 3 - 7 x } { 10 } - \frac { x + 1 } { 2 }$$

Whakaoti mō x

$$x=-1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10,2.

$$40-2\left(7-3x\right)=30-\left(3-7x\right)-5\left(x+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 7-3x.

$$40-14+6x=30-\left(3-7x\right)-5\left(x+1\right)$$

Tangohia te 14 i te 40, ka 26.

$$26+6x=30-\left(3-7x\right)-5\left(x+1\right)$$

Hei kimi i te tauaro o 3-7x, kimihia te tauaro o ia taurangi.

$$26+6x=30-3-\left(-7x\right)-5\left(x+1\right)$$

Ko te tauaro o -7x ko 7x.

$$26+6x=30-3+7x-5\left(x+1\right)$$

Tangohia te 3 i te 30, ka 27.

$$26+6x=27+7x-5\left(x+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x+1.

$$26+6x=27+7x-5x-5$$

Pahekotia te 7x me -5x, ka 2x.

$$26+6x=27+2x-5$$

Tangohia te 5 i te 27, ka 22.

$$26+6x=22+2x$$

Tangohia te 2x mai i ngā taha e rua.

$$26+6x-2x=22$$

Pahekotia te 6x me -2x, ka 4x.

$$26+4x=22$$

Tangohia te 26 mai i ngā taha e rua.

$$4x=22-26$$

Tangohia te 26 i te 22, ka -4.

$$4x=-4$$

Whakawehea ngā taha e rua ki te 4.

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

Whakawehea te -4 ki te 4, kia riro ko -1.

$$x=-1$$
