7x-6y=0
Pahekotia te 9x me -2x, ka 7x.
7x=6y
Me tāpiri te 6y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{7x}{7}=\frac{6y}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{6y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
7x-6y=0
Pahekotia te 9x me -2x, ka 7x.
-6y=-7x
Tangohia te 7x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-6y}{-6}=-\frac{7x}{-6}
Whakawehea ngā taha e rua ki te -6.
y=-\frac{7x}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=\frac{7x}{6}
Whakawehe -7x ki te -6.
