Tohaina
Kua tāruatia ki te papatopenga
5w+7=4
Pahekotia te 8w me -3w, ka 5w.
5w=4-7
Tangohia te 7 mai i ngā taha e rua.
5w=-3
Tangohia te 7 i te 4, ka -3.
w=\frac{-3}{5}
Whakawehea ngā taha e rua ki te 5.
w=-\frac{3}{5}
Ka taea te hautanga \frac{-3}{5} te tuhi anō ko -\frac{3}{5} mā te tango i te tohu tōraro.
