Question

if the value of x is 5 so find the value of y.?

Answer 1

Step-by-step explanation:

This is a very difficult and a strenuous sum that has been asked .

But yes , it has a solution too.

It is a sum of linear equation where x value is 5.

The value of y should be such that it satisfies the given equation.

x- y=10

We will then substitute the value of x that is 5.

Now, 5 -y= 10

We need to take 10 on the other side and same with y.

Now , the equation becomes

- y = 10 - 5

-y = 5

So the value of y = -5

x- y = 1o

5 - ( -5) =10

Negative sign * negative side = positive side

5 + 5= 10

LHS =RHS

Hence , the value of y that is -5 satisfies the equation x - y =10

Answer 2

Answer:

Given:

x=5 and

x-y=10 →(1)

To find:

The value of y=?

Proof:

Substitute the given x value in (1) equation

Thus we get,

5-y=10

Shift the variable one side and numbers in one side so we get,

-y=10–5

While shifting the number from one side to an another side then it automatically change its sign from positive to negative and vice versa

-y=5

We need the value of y not -y

Therefore we can write

y=-5

Thus the value of y=-5
