Kua tāruatia ki te papatopenga
16x-5-18x=-2
Tangohia te 18x mai i ngā taha e rua.
-2x-5=-2
Pahekotia te 16x me -18x, ka -2x.
-2x=-2+5
Me tāpiri te 5 ki ngā taha e rua.
-2x=3
Tāpirihia te -2 ki te 5, ka 3.
x=\frac{3}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{3}{2}
Ka taea te hautanga \frac{3}{-2} te tuhi anō ko -\frac{3}{2} mā te tango i te tohu tōraro.
