4n-12=8\left(n+4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te n-3.
4n-12=8n+32
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te n+4.
4n-12-8n=32
Tangohia te 8n mai i ngā taha e rua.
-4n-12=32
Pahekotia te 4n me -8n, ka -4n.
-4n=32+12
Me tāpiri te 12 ki ngā taha e rua.
-4n=44
Tāpirihia te 32 ki te 12, ka 44.
n=\frac{44}{-4}
Whakawehea ngā taha e rua ki te -4.
n=-11
Whakawehea te 44 ki te -4, kia riro ko -11.
