Kua tāruatia ki te papatopenga
3x=7+6y
Me tāpiri te 6y ki ngā taha e rua.
3x=6y+7
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{6y+7}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{6y+7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=2y+\frac{7}{3}
Whakawehe 7+6y ki te 3.
-6y=7-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{-6y}{-6}=\frac{7-3x}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{7-3x}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=\frac{x}{2}-\frac{7}{6}
Whakawehe 7-3x ki te -6.
