What is the value of x in the equation x – y = 30, when y = 15? 4880200

x = 45

Step-by-step explanation:

So we can get rid of y altogether, and plug in 15.

x - 15 = 30

Then, we can rearrange the equation like this:

30 + 15 = x

Now, we just add 30 + 15, and then we know what x is!

30 + 15 = 45

So x = 45!
