2\left(2x-3\right)<3\left(5-x\right)
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.
4x-6<3\left(5-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-3.
4x-6<15-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5-x.
4x-6+3x<15
Me tāpiri te 3x ki ngā taha e rua.
7x-6<15
Pahekotia te 4x me 3x, ka 7x.
7x<15+6
Me tāpiri te 6 ki ngā taha e rua.
7x<21
Tāpirihia te 15 ki te 6, ka 21.
x<\frac{21}{7}
Whakawehea ngā taha e rua ki te 7. I te mea he tōrunga te 7, kāore e huri te ahunga koreōrite.
x<3
Whakawehea te 21 ki te 7, kia riro ko 3.
