Whakaoti i te 18(11x+21)=-26(x-4)

$$18 ( 11 x + 21 ) = - 26 ( x - 4 )$$

Whakaoti mō x

$$x = -\frac{137}{112} = -1\frac{25}{112} \approx -1.223214286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te 11x+21.

$$198x+378=-26\left(x-4\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -26 ki te x-4.

$$198x+378=-26x+104$$

Me tāpiri te 26x ki ngā taha e rua.

$$198x+378+26x=104$$

Pahekotia te 198x me 26x, ka 224x.

$$224x+378=104$$

Tangohia te 378 mai i ngā taha e rua.

$$224x=104-378$$

Tangohia te 378 i te 104, ka -274.

$$224x=-274$$

Whakawehea ngā taha e rua ki te 224.

$$x=\frac{-274}{224}$$

Whakahekea te hautanga \frac{-274}{224} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{137}{112}$$
