If 3x−3<3+
2
x
and x−2≤6+2x, then x can take which of the following values?
- A6
- B2
- C10
- D−10
Solution & Step-by-step Explanation
Let us solve the two inequalities separately.
First Inequality:
3x−3<3+
2
x
Multiply the entire inequality by 2 to clear the fraction:
6x−6<6+x
6x−x<6+6
5x<12
x<
5
12
=2.4
Second Inequality:
x−2≤6+2x
x−2x≤6+2
−x≤8
Multiplying by −1 flips the inequality sign:
x≥−8
Combining both results, the range for x is:
−8≤x<2.4
Among the given options:
A) 6 (Not in range)
B) 2 (In range)
C) 10 (Not in range)
D) −10 (Not in range)
Thus, x can take the value 2.
