Kua tāruatia ki te papatopenga
-4x+6=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-4x=2y-6
Tangohia te 6 mai i ngā taha e rua.
\frac{-4x}{-4}=\frac{2y-6}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{2y-6}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{3-y}{2}
Whakawehe -6+2y ki te -4.
-2y+6=4x
Me tāpiri te 4x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-2y=4x-6
Tangohia te 6 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{4x-6}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{4x-6}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=3-2x
Whakawehe 4x-6 ki te -2.
