2x+7-8x=2
Tangohia te 8x mai i ngā taha e rua.
-6x+7=2
Pahekotia te 2x me -8x, ka -6x.
-6x=2-7
Tangohia te 7 mai i ngā taha e rua.
-6x=-5
Tangohia te 7 i te 2, ka -5.
x=\frac{-5}{-6}
Whakawehea ngā taha e rua ki te -6.
x=\frac{5}{6}
Ka taea te hautanga \frac{-5}{-6} te whakamāmā ki te \frac{5}{6} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
