Kua tāruatia ki te papatopenga
7\left(5y+3\right)-35y=21
Whakareatia ngā taha e rua o te whārite ki te 7.
35y+21-35y=21
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 5y+3.
21=21
Pahekotia te 35y me -35y, ka 0.
\text{true}
Whakatauritea te 21 me te 21.
y\in \mathrm{C}
He pono tēnei mō tētahi y ahakoa.
