Kua tāruatia ki te papatopenga
5x+1=8y
Me tāpiri te 8y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
5x=8y-1
Tangohia te 1 mai i ngā taha e rua.
\frac{5x}{5}=\frac{8y-1}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{8y-1}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-8y+1=-5x
Tangohia te 5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-8y=-5x-1
Tangohia te 1 mai i ngā taha e rua.
\frac{-8y}{-8}=\frac{-5x-1}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{-5x-1}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{5x+1}{8}
Whakawehe -5x-1 ki te -8.
