उत्तर

The value of y for which the expressions (y – 15) and (2y + 1) become equal is –16.

Explanation:

It is given that both the expressions are equal.

So, the equation is 

⇒ y – 15 = 2y + 1

⇒ y – 2y = 1 + 15  ......[Transposing 2y to LHS and (–15) to RHS]

–y = 16

Multiplying both sides by (–1), we get

y = –16
