7-2x-5x=1
Tangohia te 5x mai i ngā taha e rua.
7-7x=1
Pahekotia te -2x me -5x, ka -7x.
-7x=1-7
Tangohia te 7 mai i ngā taha e rua.
-7x=-6
Tangohia te 7 i te 1, ka -6.
x=\frac{-6}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{6}{7}
Ka taea te hautanga \frac{-6}{-7} te whakamāmā ki te \frac{6}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
