21-14y-19y=2
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 3-2y.
21-33y=2
Pahekotia te -14y me -19y, ka -33y.
-33y=2-21
Tangohia te 21 mai i ngā taha e rua.
-33y=-19
Tangohia te 21 i te 2, ka -19.
y=\frac{-19}{-33}
Whakawehea ngā taha e rua ki te -33.
y=\frac{19}{33}
Ka taea te hautanga \frac{-19}{-33} te whakamāmā ki te \frac{19}{33} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
