Remark
You need to solve the absolute value equation.
abs(x + 1) - 3 < 4 Add 3 to both sides.
abs(x +1) < 4 + 3
abs(x+1) < 7
This can have to results.
Result One
x + 1 < 7 Subtract 1 from both sides
x < 6
Result Two
x + 1 > - 7 The sign switches. Try two values to convince yourself. x = - 7 and x = - 9
x > - 8
The answer is B
