Kua tāruatia ki te papatopenga
3x+8=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
3x=2y-8
Tangohia te 8 mai i ngā taha e rua.
\frac{3x}{3}=\frac{2y-8}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2y-8}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
-2y+8=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-2y=-3x-8
Tangohia te 8 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{-3x-8}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-3x-8}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{3x}{2}+4
Whakawehe -3x-8 ki te -2.
