Kua tāruatia ki te papatopenga
2x-22=-y
Tangohia te y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2x=-y+22
Me tāpiri te 22 ki ngā taha e rua.
2x=22-y
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{22-y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{22-y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{y}{2}+11
Whakawehe -y+22 ki te 2.
y-22=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
y=-2x+22
Me tāpiri te 22 ki ngā taha e rua.
