Whakaoti i te 2x-11x-19/4=19-2x/9

$$2 x - \frac { 11 x - 19 } { 4 } = \frac { 19 - 2 x } { 9 }$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 36, arā, te tauraro pātahi he tino iti rawa te kitea o 4,9.

$$72x-9\left(11x-19\right)=4\left(19-2x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -9 ki te 11x-19.

$$72x-99x+171=4\left(19-2x\right)$$

Pahekotia te 72x me -99x, ka -27x.

$$-27x+171=4\left(19-2x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 19-2x.

$$-27x+171=76-8x$$

Me tāpiri te 8x ki ngā taha e rua.

$$-27x+171+8x=76$$

Pahekotia te -27x me 8x, ka -19x.

$$-19x+171=76$$

Tangohia te 171 mai i ngā taha e rua.

$$-19x=76-171$$

Tangohia te 171 i te 76, ka -95.

$$-19x=-95$$

Whakawehea ngā taha e rua ki te -19.

$$x=\frac{-95}{-19}$$

Whakawehea te -95 ki te -19, kia riro ko 5.

$$x=5$$
