2\left(2x+2\right)-5\left(x-1\right)<20
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,2. I te mea he tōrunga te 10, kāore e huri te ahunga koreōrite.
4x+4-5\left(x-1\right)<20
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+2.
4x+4-5x+5<20
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-1.
-x+4+5<20
Pahekotia te 4x me -5x, ka -x.
-x+9<20
Tāpirihia te 4 ki te 5, ka 9.
-x<20-9
Tangohia te 9 mai i ngā taha e rua.
-x<11
Tangohia te 9 i te 20, ka 11.
x>-11
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
