Whakaoti mō y, z, a, b
b=9
Tohaina
Kua tāruatia ki te papatopenga
3+5y-6=21
Whakaarohia te whārite tuatahi. Whakareatia te 1 ki te 6, ka 6.
-3+5y=21
Tangohia te 6 i te 3, ka -3.
5y=21+3
Me tāpiri te 3 ki ngā taha e rua.
5y=24
Tāpirihia te 21 ki te 3, ka 24.
y=\frac{24}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{24}{5} z=9 a=9 b=9
Kua oti te pūnaha te whakatau.
