Kua tāruatia ki te papatopenga
2x+c=22
Whakareatia ngā taha e rua o te whārite ki te 2.
c=22-2x
Tangohia te 2x mai i ngā taha e rua.
2x+c=22
Whakareatia ngā taha e rua o te whārite ki te 2.
2x=22-c
Tangohia te c mai i ngā taha e rua.
\frac{2x}{2}=\frac{22-c}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{22-c}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{c}{2}+11
Whakawehe 22-c ki te 2.
