Kua tāruatia ki te papatopenga
-\frac{1}{2}x=y
Me tāpiri te y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{-\frac{1}{2}x}{-\frac{1}{2}}=\frac{y}{-\frac{1}{2}}
Me whakarea ngā taha e rua ki te -2.
x=\frac{y}{-\frac{1}{2}}
Mā te whakawehe ki te -\frac{1}{2} ka wetekia te whakareanga ki te -\frac{1}{2}.
x=-2y
Whakawehe y ki te -\frac{1}{2} mā te whakarea y ki te tau huripoki o -\frac{1}{2}.
-y=\frac{1}{2}x
Me tāpiri te \frac{1}{2}x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-y=\frac{x}{2}
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{x}{-2}
Whakawehea ngā taha e rua ki te -1.
y=\frac{x}{-2}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=-\frac{x}{2}
Whakawehe \frac{x}{2} ki te -1.
