Find the range of values of x for which (x+2)/4−2x−3/3 < 4

A.

x > -6

B.

x > -3

C.

x < 8

D.

x < 4

Correct Answer: x > -6

Explanation

x+2/4 − 2x−3/3 < 4 3(x+2)−4(2x−3)/12 < 4 3x + 6 − 8x + 12 < 48 18 − 5 x< 48 ⟹ −5 x < 48 − 18 −5x < 30 ⟹ x > −6

x+2/4 − 2x−3/3 < 4 3(x+2)−4(2x−3)/12 < 4 3x + 6 − 8x + 12 < 48 18 − 5 x< 48 ⟹ −5 x < 48 − 18 −5x < 30 ⟹ x > −6
