Kua tāruatia ki te papatopenga
x+2>9\left(1-x\right)
Tātaihia te 1-x mā te pū o 1, kia riro ko 1-x.
x+2>9-9x
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 1-x.
x+2+9x>9
Me tāpiri te 9x ki ngā taha e rua.
10x+2>9
Pahekotia te x me 9x, ka 10x.
10x>9-2
Tangohia te 2 mai i ngā taha e rua.
10x>7
Tangohia te 2 i te 9, ka 7.
x>\frac{7}{10}
Whakawehea ngā taha e rua ki te 10. I te mea he tōrunga te 10, kāore e huri te ahunga koreōrite.
