Kua tāruatia ki te papatopenga
2\left(x-1\right)+3<-30
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
2x-2+3<-30
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
2x+1<-30
Tāpirihia te -2 ki te 3, ka 1.
2x<-30-1
Tangohia te 1 mai i ngā taha e rua.
2x<-31
Tangohia te 1 i te -30, ka -31.
x<-\frac{31}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
