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