3x+1-18x=0
Tangohia te 18x mai i ngā taha e rua.
-15x+1=0
Pahekotia te 3x me -18x, ka -15x.
-15x=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1}{-15}
Whakawehea ngā taha e rua ki te -15.
x=\frac{1}{15}
Ka taea te hautanga \frac{-1}{-15} te whakamāmā ki te \frac{1}{15} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
