-16-56n=-6n+34
Whakamahia te āhuatanga tohatoha hei whakarea te -8 ki te 2+7n.
-16-56n+6n=34
Me tāpiri te 6n ki ngā taha e rua.
-16-50n=34
Pahekotia te -56n me 6n, ka -50n.
-50n=34+16
Me tāpiri te 16 ki ngā taha e rua.
-50n=50
Tāpirihia te 34 ki te 16, ka 50.
n=\frac{50}{-50}
Whakawehea ngā taha e rua ki te -50.
n=-1
Whakawehea te 50 ki te -50, kia riro ko -1.
