Question

Solve: I 2x +5 I + 6 ≥ 4

Answer 1

Answer:

Step-by-step explanation:

This is an absolute value problem.

If we begin a tentative solution by subtracting 6 from both sides, we get

I 2x +5 I + 6 ≥ 4  =>   I 2x +5 I  ≥ -2

Note well that  I 2x +5 I has a value of 0 or greater; it cannot be negative.

Thus  I 2x +5 I  ≥ -2 has no solution.
