Tohaina
Kua tāruatia ki te papatopenga
3-2x=\frac{20}{2}
Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 2.
3-2x=10
Whakawehea te 20 ki te 2, kia riro ko 10.
-2x=10-3
Tangohia te 3 mai i ngā taha e rua.
-2x=7
Tangohia te 3 i te 10, ka 7.
x=-\frac{7}{2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{7}{2} y=6 z=6 a=6 b=6 c=6 d=6
Kua oti te pūnaha te whakatau.
