Whakaoti i te {l}{1=6x}{text{Solvefor}ytext{where}}{y=x^2-5x}

$$\left. \begin{array} { l } { 1 = 6 x }\\ { \text{Solve for } y \text{ where} } \\ { y = x ^ {2} - 5 x } \end{array} \right.$$

Whakaoti mō x, y

$$y=-\frac{29}{36}\approx -0.805555556$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 6.

$$\frac{1}{6}=x$$

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

$$x=\frac{1}{6}$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$y=\left(\frac{1}{6}\right)^{2}-5\times \frac{1}{6}$$

Tātaihia te \frac{1}{6} mā te pū o 2, kia riro ko \frac{1}{36}.

$$y=\frac{1}{36}-5\times \frac{1}{6}$$

Whakareatia te -5 ki te \frac{1}{6}, ka -\frac{5}{6}.

$$y=\frac{1}{36}-\frac{5}{6}$$

Tangohia te \frac{5}{6} i te \frac{1}{36}, ka -\frac{29}{36}.

$$y=-\frac{29}{36}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{1}{6} y=-\frac{29}{36}$$
