18x=7-6y
Tangohia te 6y mai i ngā taha e rua.
\frac{18x}{18}=\frac{7-6y}{18}
Whakawehea ngā taha e rua ki te 18.
x=\frac{7-6y}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
x=-\frac{y}{3}+\frac{7}{18}
Whakawehe 7-6y ki te 18.
6y=7-18x
Tangohia te 18x mai i ngā taha e rua.
\frac{6y}{6}=\frac{7-18x}{6}
Whakawehea ngā taha e rua ki te 6.
y=\frac{7-18x}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
y=\frac{7}{6}-3x
Whakawehe 7-18x ki te 6.
