Kua tāruatia ki te papatopenga
1=-\frac{3}{4}x-2
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
-\frac{3}{4}x-2=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{3}{4}x=1+2
Me tāpiri te 2 ki ngā taha e rua.
-\frac{3}{4}x=3
Tāpirihia te 1 ki te 2, ka 3.
x=3\left(-\frac{4}{3}\right)
Me whakarea ngā taha e rua ki te -\frac{4}{3}, te tau utu o -\frac{3}{4}.
x=-4
Whakareatia te 3 ki te -\frac{4}{3}, ka -4.
y=1 x=-4
Kua oti te pūnaha te whakatau.
