x+3=-3y
Tangohia te 3y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-3y-3
Tangohia te 3 mai i ngā taha e rua.
3y+3=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3y=-x-3
Tangohia te 3 mai i ngā taha e rua.
\frac{3y}{3}=\frac{-x-3}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-x-3}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{x}{3}-1
Whakawehe -x-3 ki te 3.
