Question: 6

| x + 3 | = 4 should be equal to
  • 1 and 7
  • 2 and 5
  • 1 and −7
  • 0 and −5

  Show/Hide Explanation 

Correct Answer: C

| x + 3 | = 4

±(x + 3) = 4

First taking positive

+(x + 3) = 4

x = 4 - 3

x = 1

Now by taking negative

-(x + 3) = 4

-x -3 = 4

-x = 4 + 3

x = -7

So x = 1 and -7
