Whakaoti mō b
b=\frac{1}{2}=0.5
Tohaina
Kua tāruatia ki te papatopenga
10-5b+3b=9
Me tāpiri te 3b ki ngā taha e rua.
10-2b=9
Pahekotia te -5b me 3b, ka -2b.
-2b=9-10
Tangohia te 10 mai i ngā taha e rua.
-2b=-1
Tangohia te 10 i te 9, ka -1.
b=\frac{-1}{-2}
Whakawehea ngā taha e rua ki te -2.
b=\frac{1}{2}
Ka taea te hautanga \frac{-1}{-2} te whakamāmā ki te \frac{1}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
