Question

Is |4x+2|+6=0 no solution, all real numbers, 0, and 2

Answer 1

                                        |4x + 2| + 6 = 0

Subtract  6  from each side:  |4x + 2| = -6

But the absolute value of a number is always positive.
No value of 'x' can ever make  |4x + 2|  negative.

So the equation has no solution.
