If 2x−3(2x−2)>x−1<2+2x; then x can take which of the following values?
- A2
- B-2
- C4
- D-4
Solution & Step-by-step Explanation
Let's break down the compound inequality into two parts:
Part 1:
2x−3(2x−2)>x−1
2x−6x+6>x−1
−4x+6>x−1
6+1>x+4x
7>5x⟹x<
5
7
⟹x<1.4
Part 2:
x−1<2+2x
−1−2<2x−x
−3−3
Combining both results, we find the range for x:
−3Now let's check which option falls inside this range (−3,1.4):
A) 2 (False, as 2>1.4)
B) −2 (True, as −3<−2<1.4)
C) 4 (False)
D) −4 (False, as −4<−3)
Thus, x can take the value −2.
Part 1:
2x−3(2x−2)>x−1
2x−6x+6>x−1
−4x+6>x−1
6+1>x+4x

⟹x<1.4
Part 2:
x−1<2+2x
−1−2<2x−x
−3
Combining both results, we find the range for x:
−3
A) 2 (False, as 2>1.4)
B) −2 (True, as −3<−2<1.4)
C) 4 (False)
D) −4 (False, as −4<−3)
Thus, x can take the value −2.
