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