-9x=45-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{-9x}{-9}=\frac{45-5y}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{45-5y}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{5y}{9}-5
Whakawehe 45-5y ki te -9.
5y=45+9x
Me tāpiri te 9x ki ngā taha e rua.
5y=9x+45
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{9x+45}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{9x+45}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=\frac{9x}{5}+9
Whakawehe 45+9x ki te 5.
