Kua tāruatia ki te papatopenga
nx+5-n=-2x
Tangohia te n mai i ngā taha e rua.
nx-n=-2x-5
Tangohia te 5 mai i ngā taha e rua.
\left(x-1\right)n=-2x-5
Pahekotia ngā kīanga tau katoa e whai ana i te n.
\frac{\left(x-1\right)n}{x-1}=\frac{-2x-5}{x-1}
Whakawehea ngā taha e rua ki te x-1.
n=\frac{-2x-5}{x-1}
Mā te whakawehe ki te x-1 ka wetekia te whakareanga ki te x-1.
n=-\frac{2x+5}{x-1}
Whakawehe -2x-5 ki te x-1.
nx+5+2x=n
Me tāpiri te 2x ki ngā taha e rua.
nx+2x=n-5
Tangohia te 5 mai i ngā taha e rua.
\left(n+2\right)x=n-5
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(n+2\right)x}{n+2}=\frac{n-5}{n+2}
Whakawehea ngā taha e rua ki te n+2.
x=\frac{n-5}{n+2}
Mā te whakawehe ki te n+2 ka wetekia te whakareanga ki te n+2.
