Answer:
The value of x is:

Explanation:
We are given a linear equation in terms of variable x and y as follows:

Now, we are asked to find the value of x for the given value of y.
i.e. we have to evaluate the given equation for the given value of y.
Now we are given: y= 15
so by putting this value in equation (1) we have:

On adding 15 on both the sides of the equation we have:
