Answer :

Let's analyze and solve the equation step-by-step to determine the number of solutions for [tex]\( 5 - x = -2 \)[/tex].

### Step-by-Step Solution:

1. Start with the given equation:
[tex]\[ 5 - x = -2 \][/tex]

2. Isolate the variable [tex]\( x \)[/tex]:
To isolate [tex]\( x \)[/tex], we need to get the [tex]\( x \)[/tex]-term by itself on one side of the equation. We'll first subtract 5 from both sides:

[tex]\[ 5 - x - 5 = -2 - 5 \][/tex]

Simplifying both sides, we get:

[tex]\[ -x = -7 \][/tex]

3. Solve for [tex]\( x \)[/tex]:
To solve for [tex]\( x \)[/tex], we need to get rid of the negative sign in front of [tex]\( x \)[/tex]. We do this by multiplying both sides of the equation by -1:

[tex]\[ -1 \cdot (-x) = -1 \cdot (-7) \][/tex]

Simplifying both sides, we get:

[tex]\[ x = 7 \][/tex]

### Conclusion:

By solving the equation [tex]\( 5 - x = -2 \)[/tex], we find that [tex]\( x = 7 \)[/tex].

This is a single solution, which means the equation has a unique solution. Therefore, the number of solutions to the equation [tex]\( 5 - x = -2 \)[/tex] is:

[tex]\[ \text{Unique solution} \][/tex]
