Question
The value of y for which the expressions (y – 15) and (2y + 1) become equal is ______.
Options
0
16
8
–16
Solution
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
