Kua tāruatia ki te papatopenga
6x-18-8x=13
Tangohia te 8x mai i ngā taha e rua.
-2x-18=13
Pahekotia te 6x me -8x, ka -2x.
-2x=13+18
Me tāpiri te 18 ki ngā taha e rua.
-2x=31
Tāpirihia te 13 ki te 18, ka 31.
x=\frac{31}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{31}{2}
Ka taea te hautanga \frac{31}{-2} te tuhi anō ko -\frac{31}{2} mā te tango i te tohu tōraro.
