Tohaina
Kua tāruatia ki te papatopenga
1-6r+3r=-4
Me tāpiri te 3r ki ngā taha e rua.
1-3r=-4
Pahekotia te -6r me 3r, ka -3r.
-3r=-4-1
Tangohia te 1 mai i ngā taha e rua.
-3r=-5
Tangohia te 1 i te -4, ka -5.
r=\frac{-5}{-3}
Whakawehea ngā taha e rua ki te -3.
r=\frac{5}{3}
Ka taea te hautanga \frac{-5}{-3} te whakamāmā ki te \frac{5}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
