x-2y=-1 if y=1/2 what is the value of x

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

x-2y=-1

x=-1+2y_______

$➪x = - 1 + 2y$

$➪x = - 1 + 2 \frac{1}{2} = - 1 + \frac{2}{2} = - 1 + 1 = 0$

➪0 is the answer of your question.

Hope it helps you..!!!

Answer 2

Answer:

The value of y = 0

Step-by-step explanation:

Given that:-

$x-2y=-1$

The value of y as $\frac{1}{2}$,

To find:- The value of the expression:

As we have,

=> $x-2y=-1$

Now, plug the value of y as $\frac{1}{2}$ in the above equation:

=> $x-2(\frac{1}{2}) =-1$

By further simplifying it, we get

=> $x-1=-1$

Transposing $-1$ to the right side,

=> $x = -1+1$

=> $x = 0$

Hence, the required solution is 0.
