18z-2\left(z-1\right)=2\left(8z+1\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3.
18z-2z+2=2\left(8z+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te z-1.
16z+2=2\left(8z+1\right)
Pahekotia te 18z me -2z, ka 16z.
16z+2=16z+2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 8z+1.
16z+2-16z=2
Tangohia te 16z mai i ngā taha e rua.
2=2
Pahekotia te 16z me -16z, ka 0.
\text{true}
Whakatauritea te 2 me te 2.
z\in \mathrm{C}
He pono tēnei mō tētahi z ahakoa.
