What values can be selected for x in the equation x + 72 = 36?

To solve the equation x + 72 = 36, we need to isolate the variable x. We can do this by performing some basic arithmetic operations.

First, we will subtract 72 from both sides of the equation:

x + 72 - 72 = 36 - 72

This simplifies to:

x = 36 - 72

Now, we calculate the right side:

x = -36

Hence, the only value of x that satisfies the equation x + 72 = 36 is:

x = -36

In summary, by isolating x and performing the subtraction, we find that the value of x is -36.
