Kua tāruatia ki te papatopenga
7x=8y
Me tāpiri te 8y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{7x}{7}=\frac{8y}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{8y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-8y=-7x
Tangohia te 7x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-8y}{-8}=-\frac{7x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=-\frac{7x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{7x}{8}
Whakawehe -7x ki te -8.
