Kua tāruatia ki te papatopenga
1-x-2x=-3
Tangohia te 2x mai i ngā taha e rua.
1-3x=-3
Pahekotia te -x me -2x, ka -3x.
-3x=-3-1
Tangohia te 1 mai i ngā taha e rua.
-3x=-4
Tangohia te 1 i te -3, ka -4.
x=\frac{-4}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{4}{3}
Ka taea te hautanga \frac{-4}{-3} te whakamāmā ki te \frac{4}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
