Kua tāruatia ki te papatopenga
5x+1-3x=-4
Tangohia te 3x mai i ngā taha e rua.
2x+1=-4
Pahekotia te 5x me -3x, ka 2x.
2x=-4-1
Tangohia te 1 mai i ngā taha e rua.
2x=-5
Tangohia te 1 i te -4, ka -5.
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.
