Given : | 3 x + 1 | = 0 , | 5x + 2 | = - 6 , | 2x - 1 | = 5 , x/2 - 1 = 15
To find : Which Equation has two solution
Solution:
| 3 x + 1 | = 0
=> 3x + 1 = 0
=> x = - 1/3
| 5x + 2 | = - 6 has no solution as | | is always positive
| 2x - 1 | = 5
=> 2x - 1 = 5 or 2x - 1 = - 5
=> x = 3 or x = -2
x/2 - 1 = 15
=> x = 32
| 2x - 1 | = 5 has two solutions 3 & - 2
