Whakaoti mō m
m = -\frac{9}{2} = -4\frac{1}{2} = -4.5
Tohaina
Kua tāruatia ki te papatopenga
7m-6-5m=-15
Tangohia te 5m mai i ngā taha e rua.
2m-6=-15
Pahekotia te 7m me -5m, ka 2m.
2m=-15+6
Me tāpiri te 6 ki ngā taha e rua.
2m=-9
Tāpirihia te -15 ki te 6, ka -9.
m=\frac{-9}{2}
Whakawehea ngā taha e rua ki te 2.
m=-\frac{9}{2}
Ka taea te hautanga \frac{-9}{2} te tuhi anō ko -\frac{9}{2} mā te tango i te tohu tōraro.
