4x=1+2y
Me tāpiri te 2y ki ngā taha e rua.
4x=2y+1
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{2y+1}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{2y+1}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{y}{2}+\frac{1}{4}
Whakawehe 1+2y ki te 4.
-2y=1-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{1-4x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{1-4x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=2x-\frac{1}{2}
Whakawehe 1-4x ki te -2.
