5x-25=-5y
Tangohia te 5y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5x=-5y+25
Me tāpiri te 25 ki ngā taha e rua.
5x=25-5y
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{25-5y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{25-5y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=5-y
Whakawehe -5y+25 ki te 5.
5y-25=-5x
Tangohia te 5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5y=-5x+25
Me tāpiri te 25 ki ngā taha e rua.
5y=25-5x
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{25-5x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{25-5x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=5-x
Whakawehe -5x+25 ki te 5.
