Kua tāruatia ki te papatopenga
3x+7=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
3x=3y-7
Tangohia te 7 mai i ngā taha e rua.
\frac{3x}{3}=\frac{3y-7}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{3y-7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=y-\frac{7}{3}
Whakawehe 3y-7 ki te 3.
-3y+7=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-3y=-3x-7
Tangohia te 7 mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{-3x-7}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-3x-7}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=x+\frac{7}{3}
Whakawehe -3x-7 ki te -3.
