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.
\frac{-6y}{-6}=\frac{42-7x}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{42-7x}{-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.
