Whakaoti i te {l}{y=x-p/2}{y=2p}

$$\left\{ \begin{array} { l } { y = x - \frac { p } { 2 } } \\ { y = 2 p } \end{array} \right.$$

Whakaoti mō x, y

$$x=\frac{5p}{2}$$

$$y=2p$$

Ngā Upane e Whakamahi ana i te Whakakapinga

Whakaarohia te whārite tuatahi. Tangohia te x mai i ngā taha e rua.

$$y-x=-\frac{p}{2}$$

Whakareatia ngā taha e rua o te whārite ki te 2.

$$2y-2x=-p$$

Hei whakaoti i ētahi whārite takirua mā te whakakapinga, me whakaoti tētahi whārite i te tuatahi mō tētahi o ngā taurangi. Ka whakakapi i te otinga mō taua taurangi ki tērā o ngā whārite.

$$y=2p,2y-2x=-p$$

Tīpakohia tētahi o ngā whārite e rua he māmā ake ki te whakaoti mō te y mā te wehe i te y i te taha mauī o te tohu ōrite.

$$y=2p$$

Whakakapia te 2p mō te y ki tērā atu whārite, 2y-2x=-p.

$$2\times 2p-2x=-p$$

Whakareatia 2 ki te 2p.

$$4p-2x=-p$$

Me tango 4p mai i ngā taha e rua o te whārite.

$$-2x=-5p$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{5p}{2}$$

Kua oti te pūnaha te whakatau.

$$y=2p,x=\frac{5p}{2}$$
