8\left(x-4\right)+72\leq 3x
Me whakarea ngā taha e rua o te whārite ki te 24, arā, te tauraro pātahi he tino iti rawa te kitea o 3,8. Nō te mea he >0 te 24, ka noho pērā tonu te ahunga koreōrite.
8x-32+72\leq 3x
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-4.
8x+40\leq 3x
Tāpirihia te -32 ki te 72, ka 40.
8x+40-3x\leq 0
Tangohia te 3x mai i ngā taha e rua.
5x+40\leq 0
Pahekotia te 8x me -3x, ka 5x.
5x\leq -40
Tangohia te 40 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x\leq \frac{-40}{5}
Whakawehea ngā taha e rua ki te 5. Nō te mea he >0 te 5, ka noho pērā tonu te ahunga koreōrite.
x\leq -8
Whakawehea te -40 ki te 5, kia riro ko -8.
