-7x=35-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{-7x}{-7}=\frac{35-5y}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{35-5y}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
x=\frac{5y}{7}-5
Whakawehe 35-5y ki te -7.
5y=35+7x
Me tāpiri te 7x ki ngā taha e rua.
5y=7x+35
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{7x+35}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{7x+35}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=\frac{7x}{5}+7
Whakawehe 35+7x ki te 5.
