6x+9y-7x=0
Tangohia te 7x mai i ngā taha e rua.
-x+9y=0
Pahekotia te 6x me -7x, ka -x.
-x=-9y
Tangohia te 9y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-x}{-1}=-\frac{9y}{-1}
Whakawehea ngā taha e rua ki te -1.
x=-\frac{9y}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=9y
Whakawehe -9y ki te -1.
9y=7x-6x
Tangohia te 6x mai i ngā taha e rua.
9y=x
Pahekotia te 7x me -6x, ka x.
\frac{9y}{9}=\frac{x}{9}
Whakawehea ngā taha e rua ki te 9.
y=\frac{x}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
