Whakaoti i te {l}{x^2-3b=0}{x-15=0}

$$\left. \begin{array} { l } { x ^ { 2 } - 3 b = 0 } \\ { x - 15 = 0 } \end{array} \right.$$

Whakaoti mō x, b

$$x=15$$

$$b=75$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Me tāpiri te 15 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$x=15$$

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

$$15^{2}-3b=0$$

Tātaihia te 15 mā te pū o 2, kia riro ko 225.

$$225-3b=0$$

Tangohia te 225 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-3b=-225$$

Whakawehea ngā taha e rua ki te -3.

$$b=\frac{-225}{-3}$$

Whakawehea te -225 ki te -3, kia riro ko 75.

$$b=75$$

Kua oti te pūnaha te whakatau.

$$x=15 b=75$$
