Kua tāruatia ki te papatopenga
4x-13-15x=3
Tangohia te 15x mai i ngā taha e rua.
-11x-13=3
Pahekotia te 4x me -15x, ka -11x.
-11x=3+13
Me tāpiri te 13 ki ngā taha e rua.
-11x=16
Tāpirihia te 3 ki te 13, ka 16.
x=\frac{16}{-11}
Whakawehea ngā taha e rua ki te -11.
x=-\frac{16}{11}
Ka taea te hautanga \frac{16}{-11} te tuhi anō ko -\frac{16}{11} mā te tango i te tohu tōraro.
