To solve the equation x + 2 1/2 = 8, we need to isolate x on one side.
First, we can convert 2 1/2 to a single fraction. The number 2 represents 2 whole units, and 1/2 represents half of a unit. So, 2 1/2 can be written as 2 + 1/2, which is equal to 2.5.
The equation can now be rewritten as:
x + 2.5 = 8
To isolate x, we subtract 2.5 from both sides of the equation:
x + 2.5 - 2.5 = 8 - 2.5
x = 5.5
Therefore, the solution to the equation x + 2 1/2 = 8 is x = 5.5.
