Kua tāruatia ki te papatopenga
7x=3+5y
Me tāpiri te 5y ki ngā taha e rua.
7x=5y+3
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{5y+3}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{5y+3}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-5y=3-7x
Tangohia te 7x mai i ngā taha e rua.
\frac{-5y}{-5}=\frac{3-7x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{3-7x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{7x-3}{5}
Whakawehe 3-7x ki te -5.
