Tohaina
Kua tāruatia ki te papatopenga
3x=x-5
Whakareatia ngā taha e rua o te whārite ki te 4.
3x-x=-5
Tangohia te x mai i ngā taha e rua.
2x=-5
Pahekotia te 3x me -x, ka 2x.
x=\frac{-5}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{5}{2}
Ka taea te hautanga \frac{-5}{2} te tuhi anō ko -\frac{5}{2} mā te tango i te tohu tōraro.
