Answer 2

Answer:

-1 is the required value of y.

Explanation:

Given that, $\frac{2y +5}{y + 4}$ = 1

So, we first solve the given it and find out the value of y.

• Where y is a variable and a variable in mathematics is a sign and placeholder for a variable quantity or other mathematical object.

• A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.

⇒$\frac{2y +5}{y + 4}$ = 1

⇒2y + 5 = (y + 4)

⇒2y-y = 4 - 5

⇒y = -1.

So, after solving it we get y = -1

Now, according to the question, we verify the result which is correct or not.

Verify:

We have, y = -1

And given in the question,

$\frac{2y +5}{y + 4}$ = 1

So, we need to solve the LHS

Now, on putting the value of y = -1 we get,

⇒$\frac{2(-1) +5}{(-1)+ 4}$ = $\frac{-2+ 5}{-1+ 4}$ = $\frac{3}{3}$ = 1.

So, here we proved that, LHS = RHS =1.

Hence,  -1 is the required value of y.
