Kua tāruatia ki te papatopenga
3\times 3x-42\leq 2\left(4x+1\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
9x-42\leq 2\left(4x+1\right)
Whakareatia te 3 ki te 3, ka 9.
9x-42\leq 8x+2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x+1.
9x-42-8x\leq 2
Tangohia te 8x mai i ngā taha e rua.
x-42\leq 2
Pahekotia te 9x me -8x, ka x.
x\leq 2+42
Me tāpiri te 42 ki ngā taha e rua.
x\leq 44
Tāpirihia te 2 ki te 42, ka 44.
