What is the value of x in the equation x – y = 30, when y = 15? a.4 b.8 c.80 d. 200

The value of x is:

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:

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

what are ur choices?
