Find the range of values of x which satisfy the inequalities 4x – 7 (leq) 3x and 3x – 4 (leq) 4x
-
A.
-4 (leq) x (leq) 7 -
B.
-7 (leq) x (leq) 4 -
C.
x (geq) -7 -
D.
-7 (leq) x (leq) 6
Correct Answer: Option A
Explanation
4X – 7 (leq) 3X and 3X – 4 (leq) 4X
4X – 3X (leq) 7 and 3X – 4X (leq) 4
X (leq) 7 and -X (leq) 4 = X (geq) -4
Range -4 (leq) x (leq) 7
