What is 4x +2 = 9x + 5

This is a challenge whoever gets it right gets why not

What is 4x +2 = 9x + 5

⇒ 4x + 2 = 9x + 5

Now, subtract 2 from both Left Hand Side and Right Hand Side to eliminate + 2 in Left Hand Side,

⇒ 4x + 2 - 2 = 9x + 5 - 2

⇒ 4x = 9x + 3

Now, subtract 9x from both Left Hand Side and Right Hand Side to eliminate 9x in Right Hand Side,

⇒ 4x - 9x = 9x - 9x + 3

⇒ - 5x = 3

Now, Transpose - 5 to Right Hand Side,

⇒ x =

∴ x =

Value of 'x' is .
