Whakaoti i te ((0*x)+(1*5)+(2*6)+(3*3)+(4*2))div(x+5+6+3+2)=2

$$( ( 0 \times x ) + ( 1 \times 5 ) + ( 2 \times 6 ) + ( 3 \times 3 ) + ( 4 \times 2 ) ) \div ( x + 5 + 6 + 3 + 2 ) = 2$$

Whakaoti mō x

$$x=1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -16 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+16.

$$0x+1\times 5+2\times 6+3\times 3+4\times 2=2\left(x+16\right)$$

Mahia ngā whakarea.

$$0x+5+12+9+8=2\left(x+16\right)$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0+5+12+9+8=2\left(x+16\right)$$

Tāpirihia te 0 ki te 5, ka 5.

$$5+12+9+8=2\left(x+16\right)$$

Tāpirihia te 5 ki te 12, ka 17.

$$17+9+8=2\left(x+16\right)$$

Tāpirihia te 17 ki te 9, ka 26.

$$26+8=2\left(x+16\right)$$

Tāpirihia te 26 ki te 8, ka 34.

$$34=2\left(x+16\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+16.

$$34=2x+32$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$2x+32=34$$

Tangohia te 32 mai i ngā taha e rua.

$$2x=34-32$$

Tangohia te 32 i te 34, ka 2.

$$2x=2$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{2}{2}$$

Whakawehea te 2 ki te 2, kia riro ko 1.

$$x=1$$
