Kua tāruatia ki te papatopenga
4x+12=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
4x=3y-12
Tangohia te 12 mai i ngā taha e rua.
\frac{4x}{4}=\frac{3y-12}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{3y-12}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{3y}{4}-3
Whakawehe -12+3y ki te 4.
-3y+12=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-3y=-4x-12
Tangohia te 12 mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{-4x-12}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-4x-12}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{4x}{3}+4
Whakawehe -4x-12 ki te -3.
