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