Kua tāruatia ki te papatopenga
-x-81=7x+102+65x
Pahekotia te 5x me -6x, ka -x.
-x-81=72x+102
Pahekotia te 7x me 65x, ka 72x.
-x-81-72x=102
Tangohia te 72x mai i ngā taha e rua.
-73x-81=102
Pahekotia te -x me -72x, ka -73x.
-73x=102+81
Me tāpiri te 81 ki ngā taha e rua.
-73x=183
Tāpirihia te 102 ki te 81, ka 183.
x=\frac{183}{-73}
Whakawehea ngā taha e rua ki te -73.
x=-\frac{183}{73}
Ka taea te hautanga \frac{183}{-73} te tuhi anō ko -\frac{183}{73} mā te tango i te tohu tōraro.
