5n-40=-31+8n
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te n-8.
5n-40-8n=-31
Tangohia te 8n mai i ngā taha e rua.
-3n-40=-31
Pahekotia te 5n me -8n, ka -3n.
-3n=-31+40
Me tāpiri te 40 ki ngā taha e rua.
-3n=9
Tāpirihia te -31 ki te 40, ka 9.
n=\frac{9}{-3}
Whakawehea ngā taha e rua ki te -3.
n=-3
Whakawehea te 9 ki te -3, kia riro ko -3.
