x+12=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-2y-12
Tangohia te 12 mai i ngā taha e rua.
2y+12=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-x-12
Tangohia te 12 mai i ngā taha e rua.
\frac{2y}{2}=\frac{-x-12}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{-x-12}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{x}{2}-6
Whakawehe -x-12 ki te 2.
