Kua tāruatia ki te papatopenga
2x-1=4y
Me tāpiri te 4y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
2x=4y+1
Me tāpiri te 1 ki ngā taha e rua.
\frac{2x}{2}=\frac{4y+1}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{4y+1}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=2y+\frac{1}{2}
Whakawehe 4y+1 ki te 2.
-4y-1=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-4y=-2x+1
Me tāpiri te 1 ki ngā taha e rua.
-4y=1-2x
He hanga arowhānui tō te whārite.
\frac{-4y}{-4}=\frac{1-2x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{1-2x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x}{2}-\frac{1}{4}
Whakawehe -2x+1 ki te -4.
