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