3n=7x-5x
Tangohia te 5x mai i ngā taha e rua.
3n=2x
Pahekotia te 7x me -5x, ka 2x.
\frac{3n}{3}=\frac{2x}{3}
Whakawehea ngā taha e rua ki te 3.
n=\frac{2x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
3n+5x-7x=0
Tangohia te 7x mai i ngā taha e rua.
3n-2x=0
Pahekotia te 5x me -7x, ka -2x.
-2x=-3n
Tangohia te 3n mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-2x}{-2}=-\frac{3n}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{3n}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{3n}{2}
Whakawehe -3n ki te -2.
