Whakaoti i te 11*(x-1)=11-(1+x)

$$11 \cdot ( x - 1 ) = 11 - ( 1 + x )$$

Whakaoti mō x

$$x = \frac{7}{4} = 1\frac{3}{4} = 1.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 11 ki te x-1.

$$11x-11=11-\left(1+x\right)$$

Hei kimi i te tauaro o 1+x, kimihia te tauaro o ia taurangi.

$$11x-11=11-1-x$$

Tangohia te 1 i te 11, ka 10.

$$11x-11=10-x$$

Me tāpiri te x ki ngā taha e rua.

$$11x-11+x=10$$

Pahekotia te 11x me x, ka 12x.

$$12x-11=10$$

Me tāpiri te 11 ki ngā taha e rua.

$$12x=10+11$$

Tāpirihia te 10 ki te 11, ka 21.

$$12x=21$$

Whakawehea ngā taha e rua ki te 12.

$$x=\frac{21}{12}$$

Whakahekea te hautanga \frac{21}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{7}{4}$$
