Kua tāruatia ki te papatopenga
4+3x=16x
Whakareatia te 2 ki te 8, ka 16.
4+3x-16x=0
Tangohia te 16x mai i ngā taha e rua.
4-13x=0
Pahekotia te 3x me -16x, ka -13x.
-13x=-4
Tangohia te 4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-4}{-13}
Whakawehea ngā taha e rua ki te -13.
x=\frac{4}{13}
Ka taea te hautanga \frac{-4}{-13} te whakamāmā ki te \frac{4}{13} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
