x=

this is a joke, right?

subtract 15 from both sides.

okay ty

To find the value of x in the equation x + 15 = 8, you need to isolate x on one side of the equation.

Here's how you can solve it step by step:

1. Start with the equation x + 15 = 8.

2. To isolate x, you need to get rid of the 15 on the left side of the equation. You can do this by subtracting 15 from both sides of the equation.

x + 15 - 15 = 8 - 15
x = -7

Therefore, the value of x is -7.
