Alright, let's examine and solve the equation step-by-step:
Given:
[tex]\[ \} + \xi = 7 + 3 - 5 \][/tex]
First, we simplify the right-hand side of the equation:
[tex]\[ 7 + 3 - 5 \][/tex]
1. Add the numbers:
[tex]\[ 7 + 3 = 10 \][/tex]
2. Subtract 5 from the result:
[tex]\[ 10 - 5 = 5 \][/tex]
So the right-hand side simplifies to 5. Thus, our equation now looks like this:
[tex]\[ \} + \xi = 5 \][/tex]
Assuming that the left side [tex]\(\}\)[/tex] is a context or typo, we need to solve for [tex]\(\xi\)[/tex]. Since [tex]\(\}\)[/tex] does not seem to affect the equation fundamentally, we can proceed as if it is absent (or contextually understood as not contributing anything numeric).
Thus, we get:
[tex]\[ \xi = 5 \][/tex]
So, the value of [tex]\(\xi\)[/tex] is:
[tex]\[ \xi = 5 \][/tex]
