Tohaina
Kua tāruatia ki te papatopenga
5\left(z-6\right)=8\left(z-3\right)
Me whakarea ngā taha e rua o te whārite ki te 40, arā, te tauraro pātahi he tino iti rawa te kitea o 8,5.
5z-30=8\left(z-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te z-6.
5z-30=8z-24
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te z-3.
5z-30-8z=-24
Tangohia te 8z mai i ngā taha e rua.
-3z-30=-24
Pahekotia te 5z me -8z, ka -3z.
-3z=-24+30
Me tāpiri te 30 ki ngā taha e rua.
-3z=6
Tāpirihia te -24 ki te 30, ka 6.
z=\frac{6}{-3}
Whakawehea ngā taha e rua ki te -3.
z=-2
Whakawehea te 6 ki te -3, kia riro ko -2.
