Kua tāruatia ki te papatopenga
-2x+2=1-0x
Whakareatia te 0 ki te 5, ka 0.
-2x+2=1-0
Ko te tau i whakarea ki te kore ka hua ko te kore.
-2x+2=1
Tangohia te 0 i te 1, ka 1.
-2x=1-2
Tangohia te 2 mai i ngā taha e rua.
-2x=-1
Tangohia te 2 i te 1, ka -1.
x=\frac{-1}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{1}{2}
Ka taea te hautanga \frac{-1}{-2} te whakamāmā ki te \frac{1}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
