Kua tāruatia ki te papatopenga
-7x=-35+5y
Me tāpiri te 5y ki ngā taha e rua.
-7x=5y-35
He hanga arowhānui tō te whārite.
\frac{-7x}{-7}=\frac{5y-35}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{5y-35}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
x=-\frac{5y}{7}+5
Whakawehe -35+5y ki te -7.
-5y=-35+7x
Me tāpiri te 7x ki ngā taha e rua.
-5y=7x-35
He hanga arowhānui tō te whārite.
\frac{-5y}{-5}=\frac{7x-35}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{7x-35}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=-\frac{7x}{5}+7
Whakawehe -35+7x ki te -5.
