5-6x-7x=2
Tangohia te 7x mai i ngā taha e rua.
5-13x=2
Pahekotia te -6x me -7x, ka -13x.
-13x=2-5
Tangohia te 5 mai i ngā taha e rua.
-13x=-3
Tangohia te 5 i te 2, ka -3.
x=\frac{-3}{-13}
Whakawehea ngā taha e rua ki te -13.
x=\frac{3}{13}
Ka taea te hautanga \frac{-3}{-13} te whakamāmā ki te \frac{3}{13} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
