Kua tāruatia ki te papatopenga
7x=-42+6y
Me tāpiri te 6y ki ngā taha e rua.
7x=6y-42
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{6y-42}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{6y-42}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
x=\frac{6y}{7}-6
Whakawehe -42+6y ki te 7.
-6y=-42-7x
Tangohia te 7x mai i ngā taha e rua.
-6y=-7x-42
He hanga arowhānui tō te whārite.
\frac{-6y}{-6}=\frac{-7x-42}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{-7x-42}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=\frac{7x}{6}+7
Whakawehe -42-7x ki te -6.
