Whakaoti i te 32(x+10)+29x+3(x-5)=945

$$32 ( x + 10 ) + 29 x + 3 ( x - 5 ) = 945$$

Whakaoti mō x

$$x=10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 32 ki te x+10.

$$32x+320+29x+3\left(x-5\right)=945$$

Pahekotia te 32x me 29x, ka 61x.

$$61x+320+3\left(x-5\right)=945$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-5.

$$61x+320+3x-15=945$$

Pahekotia te 61x me 3x, ka 64x.

$$64x+320-15=945$$

Tangohia te 15 i te 320, ka 305.

$$64x+305=945$$

Tangohia te 305 mai i ngā taha e rua.

$$64x=945-305$$

Tangohia te 305 i te 945, ka 640.

$$64x=640$$

Whakawehea ngā taha e rua ki te 64.

$$x=\frac{640}{64}$$

Whakawehea te 640 ki te 64, kia riro ko 10.

$$x=10$$
