Réitigh do z_1,v_1,v_2,z_2.

$$z_{1}=5$$

$$v_{1}=3$$

$$v_{2}=5$$

$$z_{2}=10$$

Céimeanna Réitigh

Cuir an chéad cothromóid san áireamh. Ionsáigh luachanna aitheanta na n-athróg sa chothromóid.

$$5+\frac{3v_{2}}{2}=10+\frac{v_{2}}{2}$$

Méadaigh an dá thaobh den chothromóid faoi 2.

$$10+3v_{2}=20+v_{2}$$

Bain v_{2} ón dá thaobh.

$$10+3v_{2}-v_{2}=20$$

Comhcheangail 3v_{2} agus -v_{2} chun 2v_{2} a fháil.

$$10+2v_{2}=20$$

Bain 10 ón dá thaobh.

$$2v_{2}=20-10$$

Dealaigh 10 ó 20 chun 10 a fháil.

$$2v_{2}=10$$

Roinn an dá thaobh faoi 2.

$$v_{2}=\frac{10}{2}$$

Roinn 10 faoi 2 chun 5 a fháil.

$$v_{2}=5$$

Tá an córas réitithe anois.

$$z_{1}=5 v_{1}=3 v_{2}=5 z_{2}=10$$
