✔ 最佳答案
4 - 11 > 5x
- 7 > 5x
x < - 7/5

4 - 5x > 11
Subtract 4 from both sides:
-5x > 7
Divide by 5:
-x > 7/5
Hence:
x < -7/5 (Multiplying by negative 1 reverses the inequality)

4 - 5x >11 | -4
-5x > 11 - 4
-5x > 7 |*1/5
-x >7/5|*(-1)
x<7/5

4 - 5x > 11
5x < 4 - 11
5x < -7
x < -7/5
2008-02-26 4:10 pm
4-5 x > 11
=> 4 > 11 + 5 x
=> 4 > 11/5 + 5 x /5
=> 4 > 11/5 + x
=> x < 4 * 5/11
=> x < 20/ 11
=> x < 1. 82
