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