Kua tāruatia ki te papatopenga
2z-2=6-3\left(z+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te z-1.
2z-2=6-3z-3
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te z+1.
2z-2=3-3z
Tangohia te 3 i te 6, ka 3.
2z-2+3z=3
Me tāpiri te 3z ki ngā taha e rua.
5z-2=3
Pahekotia te 2z me 3z, ka 5z.
5z=3+2
Me tāpiri te 2 ki ngā taha e rua.
5z=5
Tāpirihia te 3 ki te 2, ka 5.
z=\frac{5}{5}
Whakawehea ngā taha e rua ki te 5.
z=1
Whakawehea te 5 ki te 5, kia riro ko 1.
