Kua tāruatia ki te papatopenga
\left(y+13\right)\times 3=16y
Tē taea kia ōrite te tāupe y ki tētahi o ngā uara -13,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 16y\left(y+13\right), arā, te tauraro pātahi he tino iti rawa te kitea o 16y,y+13.
3y+39=16y
Whakamahia te āhuatanga tohatoha hei whakarea te y+13 ki te 3.
3y+39-16y=0
Tangohia te 16y mai i ngā taha e rua.
-13y+39=0
Pahekotia te 3y me -16y, ka -13y.
-13y=-39
Tangohia te 39 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
y=\frac{-39}{-13}
Whakawehea ngā taha e rua ki te -13.
y=3
Whakawehea te -39 ki te -13, kia riro ko 3.
