Question

the value of Y at X = -1 in the equation 5Y=2 is ................ .

Answer 1

Answer:

Y=2/5

Step-by-step explanation:

The equation is 5Y=2,which has no x variable,so we can also write the equation as 0*X+5Y=2 then it will remain the same whether you put any value of x so if we solve the equation;

0*X+5Y=2

0*(-1)+5Y=2. (The value of X is -1)

5Y=2. (O multiplied by anything is zero)

Y=2/5.

Answer 2

Given:

$5y=2$

To find:

Value of $y$ at $x=-1$

Solution:

The given equation is:

$5y=2$

In the given equation, there is no term containing the variable $x$. So in this case we can write,

$0x+5y=2$

Now if we solve for $y$, we will get,

$5y=2-0x$

⇒$y=\frac{2-0x}{5}$

Now given that the value of $x=-1$, we need to find the value of $y$. Also, we must observe that any value multiplied with zero results in zero.

So, putting all the respective values we get,

$y=\frac{2-0(-1)}{5}$

⇒$y=\frac{2}{5}$

Hence, at $x=-1$, the value of $y$ is $\frac{2}{5}$.
