5 raruraru e ōrite ana ki:
\frac { x } { 2 } - \frac { 1 } { 3 } > \frac { 2 x } { 3 } + 1
Tohaina
Kua tāruatia ki te papatopenga
3x-2>2\times 2x+6
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
3x-2>4x+6
Whakareatia te 2 ki te 2, ka 4.
3x-2-4x>6
Tangohia te 4x mai i ngā taha e rua.
-x-2>6
Pahekotia te 3x me -4x, ka -x.
-x>6+2
Me tāpiri te 2 ki ngā taha e rua.
-x>8
Tāpirihia te 6 ki te 2, ka 8.
x<-8
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
