Answer :
We start with the equation
[tex]$$
x - 4 = 3.5.
$$[/tex]
To solve for [tex]$x$[/tex], we add [tex]$4$[/tex] to both sides of the equation. This gives:
[tex]$$
x - 4 + 4 = 3.5 + 4.
$$[/tex]
Simplifying both sides, we have:
[tex]$$
x = 7.5.
$$[/tex]
Thus, the solution to the equation is [tex]$\boxed{x = 7.5}$[/tex].
