If 5x−3≥3+
2
x
and 4x−2≤6+x, then x can take which of the following values?
- A1
- B2
- C−1
- D−2
Solution & Step-by-step Explanation
Solve the first inequality:
5x−3≥3+
2
x
Multiply the entire inequality by 2 to clear the fraction:
10x−6≥6+x
10x−x≥6+6
9x≥12
x≥
9
12
⟹x≥
3
4
⟹x≥1.33
Solve the second inequality:
4x−2≤6+x
4x−x≤6+2
3x≤8
x≤
3
8
⟹x≤2.67
Combining both inequalities, we get the range for x:
3
4
≤x≤
3
8
⟹1.33≤x≤2.67
Among the given options, only 2 falls within this interval.
