Solve: x+3<1x + 3 < 1 or x2>5x - 2 > 5

A

x<2x < -2 or x>7x > 7

B

x<2x < -2 or x>3x > 3

C

2<x<7-2 < x < 7

D

x<4x < 4 or x>7x > 7

Correct Answer: A

Choice A is the correct answer. Solve independently.

  1. First: x<2x < -2
  2. Second: x>7x > 7
  3. Combine: x<2x < -2 or x>7x > 7

?�� Strategic Tip: "Or" inequalities don't need to overlap.

Choice B is incorrect because it solves the second part incorrectly. Choice C is incorrect because it tries to form an "and" interval. Choice D is incorrect because it solves the first part incorrectly.
