Answer:
6.
Explanation:
To solve for x, you need to isolate x on one side of the equation by adding 4 to both sides. This gives you:
x - 4 + 4 = 2 + 4
x = 6
To check your solution, you can plug in x = 6 into the original equation and see if it is true.
6 - 4 = 2
2 = 2
This is true, so x = 6 is the correct solution.
