Let's solve the problem step-by-step.

We are given the linear equation [tex]\( x+7=12 \)[/tex].

1. Identify the equation:
- The equation is [tex]\( x+7=12 \)[/tex].

2. Isolate the variable [tex]\( x \)[/tex]:
- To isolate [tex]\( x \)[/tex], we need to get rid of the constant term on the left-hand side of the equation. In this case, the constant term is [tex]\( 7 \)[/tex].

3. Subtract 7 from both sides of the equation:
- [tex]\( x+7 - 7 = 12 - 7 \)[/tex]
- This simplifies to [tex]\( x = 5 \)[/tex].

So, the solution to the equation [tex]\( x+7=12 \)[/tex] is [tex]\( x = 5 \)[/tex].

Therefore, the correct answer is:
[tex]\[ x+7=12 ; x=5 \][/tex]
