3\left(x-1\right)+30<5x
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 5,3. I te mea he tōrunga te 15, kāore e huri te ahunga koreōrite.
3x-3+30<5x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
3x+27<5x
Tāpirihia te -3 ki te 30, ka 27.
3x+27-5x<0
Tangohia te 5x mai i ngā taha e rua.
-2x+27<0
Pahekotia te 3x me -5x, ka -2x.
-2x<-27
Tangohia te 27 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x>\frac{-27}{-2}
Whakawehea ngā taha e rua ki te -2. I te mea he tōraro a -2, ka huri te ahunga koreōrite.
x>\frac{27}{2}
Ka taea te hautanga \frac{-27}{-2} te whakamāmā ki te \frac{27}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
