Tohaina
Kua tāruatia ki te papatopenga
5t-30=3t
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 3,5.
5t-30-3t=0
Tangohia te 3t mai i ngā taha e rua.
2t-30=0
Pahekotia te 5t me -3t, ka 2t.
2t=30
Me tāpiri te 30 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
t=\frac{30}{2}
Whakawehea ngā taha e rua ki te 2.
t=15
Whakawehea te 30 ki te 2, kia riro ko 15.
