Whakaoti mō y, z, a, b, c
c=-2
Tohaina
Kua tāruatia ki te papatopenga
5y=-22+12
Whakaarohia te whārite tuatahi. Me tāpiri te 12 ki ngā taha e rua.
5y=-10
Tāpirihia te -22 ki te 12, ka -10.
y=\frac{-10}{5}
Whakawehea ngā taha e rua ki te 5.
y=-2
Whakawehea te -10 ki te 5, kia riro ko -2.
y=-2 z=-2 a=-2 b=-2 c=-2
Kua oti te pūnaha te whakatau.
