Kua tāruatia ki te papatopenga
18-4x=0.5\times 0.4\times 5
Whakareatia te 12 ki te 1.5, ka 18.
18-4x=0.2\times 5
Whakareatia te 0.5 ki te 0.4, ka 0.2.
18-4x=1
Whakareatia te 0.2 ki te 5, ka 1.
-4x=1-18
Tangohia te 18 mai i ngā taha e rua.
-4x=-17
Tangohia te 18 i te 1, ka -17.
x=\frac{-17}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{17}{4}
Ka taea te hautanga \frac{-17}{-4} te whakamāmā ki te \frac{17}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
