Kua tāruatia ki te papatopenga
-x+7=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-x=3y-7
Tangohia te 7 mai i ngā taha e rua.
\frac{-x}{-1}=\frac{3y-7}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{3y-7}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=7-3y
Whakawehe 3y-7 ki te -1.
-3y+7=x
Me tāpiri te x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-3y=x-7
Tangohia te 7 mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{x-7}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{x-7}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{7-x}{3}
Whakawehe x-7 ki te -3.
