Kua tāruatia ki te papatopenga
-18x-14+15x=-12
Me tāpiri te 15x ki ngā taha e rua.
-3x-14=-12
Pahekotia te -18x me 15x, ka -3x.
-3x=-12+14
Me tāpiri te 14 ki ngā taha e rua.
-3x=2
Tāpirihia te -12 ki te 14, ka 2.
x=\frac{2}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-\frac{2}{3}
Ka taea te hautanga \frac{2}{-3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.
