5x-20=-4y
Tangohia te 4y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5x=-4y+20
Me tāpiri te 20 ki ngā taha e rua.
5x=20-4y
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{20-4y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{20-4y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=-\frac{4y}{5}+4
Whakawehe -4y+20 ki te 5.
4y-20=-5x
Tangohia te 5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4y=-5x+20
Me tāpiri te 20 ki ngā taha e rua.
4y=20-5x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{20-5x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{20-5x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{5x}{4}+5
Whakawehe -5x+20 ki te 4.
