Kua tāruatia ki te papatopenga
1-3x=120
Pahekotia te 2x me -5x, ka -3x.
-3x=120-1
Tangohia te 1 mai i ngā taha e rua.
-3x=119
Tangohia te 1 i te 120, ka 119.
x=\frac{119}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-\frac{119}{3}
Ka taea te hautanga \frac{119}{-3} te tuhi anō ko -\frac{119}{3} mā te tango i te tohu tōraro.
