Kua tāruatia ki te papatopenga
3\left(13x-14\right)<4\left(5-x\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3. I te mea he tōrunga te 12, kāore e huri te ahunga koreōrite.
39x-42<4\left(5-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 13x-14.
39x-42<20-4x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 5-x.
39x-42+4x<20
Me tāpiri te 4x ki ngā taha e rua.
43x-42<20
Pahekotia te 39x me 4x, ka 43x.
43x<20+42
Me tāpiri te 42 ki ngā taha e rua.
43x<62
Tāpirihia te 20 ki te 42, ka 62.
x<\frac{62}{43}
Whakawehea ngā taha e rua ki te 43. I te mea he tōrunga te 43, kāore e huri te ahunga koreōrite.
