6-2x=5x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3-x.
6-2x-5x=0
Tangohia te 5x mai i ngā taha e rua.
6-7x=0
Pahekotia te -2x me -5x, ka -7x.
-7x=-6
Tangohia te 6 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
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.
