Tohaina
Kua tāruatia ki te papatopenga
4\left(n+12\right)=n
Me whakarea ngā taha e rua o te whārite ki te 16, arā, te tauraro pātahi he tino iti rawa te kitea o 4,16.
4n+48=n
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te n+12.
4n+48-n=0
Tangohia te n mai i ngā taha e rua.
3n+48=0
Pahekotia te 4n me -n, ka 3n.
3n=-48
Tangohia te 48 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
n=\frac{-48}{3}
Whakawehea ngā taha e rua ki te 3.
n=-16
Whakawehea te -48 ki te 3, kia riro ko -16.
