5 raruraru e ōrite ana ki:
2 ( 3 x + 4 ) - 5 ( x - 9 ) > 8 ( 2 x - 6 ) - 9 ( 4 x - 7 )
Tohaina
Kua tāruatia ki te papatopenga
6x+8-5\left(x-9\right)>8\left(2x-6\right)-9\left(4x-7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+4.
6x+8-5x+45>8\left(2x-6\right)-9\left(4x-7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-9.
x+8+45>8\left(2x-6\right)-9\left(4x-7\right)
Pahekotia te 6x me -5x, ka x.
x+53>8\left(2x-6\right)-9\left(4x-7\right)
Tāpirihia te 8 ki te 45, ka 53.
x+53>16x-48-9\left(4x-7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 2x-6.
x+53>16x-48-36x+63
Whakamahia te āhuatanga tohatoha hei whakarea te -9 ki te 4x-7.
x+53>-20x-48+63
Pahekotia te 16x me -36x, ka -20x.
x+53>-20x+15
Tāpirihia te -48 ki te 63, ka 15.
x+53+20x>15
Me tāpiri te 20x ki ngā taha e rua.
21x+53>15
Pahekotia te x me 20x, ka 21x.
21x>15-53
Tangohia te 53 mai i ngā taha e rua.
21x>-38
Tangohia te 53 i te 15, ka -38.
x>-\frac{38}{21}
Whakawehea ngā taha e rua ki te 21. I te mea he tōrunga te 21, kāore e huri te ahunga koreōrite.
