Kua tāruatia ki te papatopenga
3x+5=y
Me tāpiri te y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
3x=y-5
Tangohia te 5 mai i ngā taha e rua.
\frac{3x}{3}=\frac{y-5}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{y-5}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
-y+5=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-y=-3x-5
Tangohia te 5 mai i ngā taha e rua.
\frac{-y}{-1}=\frac{-3x-5}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{-3x-5}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=3x+5
Whakawehe -3x-5 ki te -1.
