Kua tāruatia ki te papatopenga
x-4x=-40
Tangohia te 4x mai i ngā taha e rua.
-3x=-40
Pahekotia te x me -4x, ka -3x.
x=\frac{-40}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{40}{3}
Ka taea te hautanga \frac{-40}{-3} te whakamāmā ki te \frac{40}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
