6\left(x-7\right)-5\left(3-2x\right)\geq 60
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,6. I te mea he tōrunga te 30, kāore e huri te ahunga koreōrite.
6x-42-5\left(3-2x\right)\geq 60
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x-7.
6x-42-15+10x\geq 60
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 3-2x.
6x-57+10x\geq 60
Tangohia te 15 i te -42, ka -57.
16x-57\geq 60
Pahekotia te 6x me 10x, ka 16x.
16x\geq 60+57
Me tāpiri te 57 ki ngā taha e rua.
16x\geq 117
Tāpirihia te 60 ki te 57, ka 117.
x\geq \frac{117}{16}
Whakawehea ngā taha e rua ki te 16. I te mea he tōrunga te 16, kāore e huri te ahunga koreōrite.
