Kua tāruatia ki te papatopenga
-50+y=18-6y
Whakareatia ngā taha e rua o te whārite ki te 2.
-50+y+6y=18
Me tāpiri te 6y ki ngā taha e rua.
-50+7y=18
Pahekotia te y me 6y, ka 7y.
7y=18+50
Me tāpiri te 50 ki ngā taha e rua.
7y=68
Tāpirihia te 18 ki te 50, ka 68.
y=\frac{68}{7}
Whakawehea ngā taha e rua ki te 7.
