3x+4-6x<-12
Tangohia te 6x mai i ngā taha e rua.
-3x+4<-12
Pahekotia te 3x me -6x, ka -3x.
-3x<-12-4
Tangohia te 4 mai i ngā taha e rua.
-3x<-16
Tangohia te 4 i te -12, ka -16.
x>\frac{-16}{-3}
Whakawehea ngā taha e rua ki te -3. I te mea he tōraro a -3, ka huri te ahunga koreōrite.
x>\frac{16}{3}
Ka taea te hautanga \frac{-16}{-3} te whakamāmā ki te \frac{16}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
