20\left(5x-2\right)-12\left(7x-3\right)>15x
Me whakarea ngā taha e rua o te whārite ki te 60, arā, te tauraro pātahi he tino iti rawa te kitea o 3,5,4. I te mea he tōrunga te 60, kāore e huri te ahunga koreōrite.
100x-40-12\left(7x-3\right)>15x
Whakamahia te āhuatanga tohatoha hei whakarea te 20 ki te 5x-2.
100x-40-84x+36>15x
Whakamahia te āhuatanga tohatoha hei whakarea te -12 ki te 7x-3.
16x-40+36>15x
Pahekotia te 100x me -84x, ka 16x.
16x-4>15x
Tāpirihia te -40 ki te 36, ka -4.
16x-4-15x>0
Tangohia te 15x mai i ngā taha e rua.
x-4>0
Pahekotia te 16x me -15x, ka x.
x>4
Me tāpiri te 4 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
