2\left(5x-7x-14\right)>3\left(4-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x+2.
2\left(-2x-14\right)>3\left(4-x\right)
Pahekotia te 5x me -7x, ka -2x.
-4x-28>3\left(4-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te -2x-14.
-4x-28>12-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4-x.
-4x-28+3x>12
Me tāpiri te 3x ki ngā taha e rua.
-x-28>12
Pahekotia te -4x me 3x, ka -x.
-x>12+28
Me tāpiri te 28 ki ngā taha e rua.
-x>40
Tāpirihia te 12 ki te 28, ka 40.
x<-40
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
