The given equation is 5x+1 + 52–x = 53 + 1

5x+1 + 52–x = 53 + 1

⇒ 5x.51+52.5–x=125+1

⇒ 5.5x +25/5^x=126

Let 5x = p



⇒ 5p2 + 25 = 126p

⇒ 5p2 – 126p + 25 = 0

⇒ 5p2 – 125p – p + 25 = 0

⇒ 5p (p – 25) –1 (p – 25) = 0

⇒ (5p – 1) (p – 25) = 0

⇒ 5p – 1= 0  or p – 25 = 0


⇒ 5x = 5–1 or 5x = 52

Comparing the indices of 5, we get

x = –1 or x = 2

Thus, the value of x is –1 or 2.


Hope it is helps.
