64-4x=3x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 16-x.
64-4x-3x=0
Tangohia te 3x mai i ngā taha e rua.
64-7x=0
Pahekotia te -4x me -3x, ka -7x.
-7x=-64
Tangohia te 64 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-64}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{64}{7}
Ka taea te hautanga \frac{-64}{-7} te whakamāmā ki te \frac{64}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
