|2x - 4| = 5 → the contents of an absolute value can be positive or negative

2x - 4 = ± 5

2x = 4 ± 5

First case: 2x = 4 + 5 → 2x = 9 → x = 9/2

Second case: 2x = 4 - 5 → 2x = - 1 → x = 1/2

|3x - 4| = - 12 → an absolute value is always ≥ 0, so it's not possible → no solution

|2x - 4| = 5

2x - 4 = 5

2x = 5 + 4

2x = 9

x = 9/2

2x - 4 = - 5

2x = - 5 + 4

2x = - 1

x = - 1/2

|3x - 4| = -12

well in this equation has a negative number to the right side of the equation, so it is impossible to solve the its values of x..

Therefore, they don't have the same answers...

Are |2x - 4| = 5

|3x - 4| = -12 the same

Nope!

|2x - 4| = 5 has 2 Real answers

|3x - 4| = -12 has none.

if 2x-4 = 15x-20 , then :

13x = 16

x = 16/13

2x-4 = (32-52)/13 = -20/13

15x-20 = (240-260)/13 = -20/13

both results ≠ -12
