I'm sorry, but it seems there is a mix of incoherent fragments in your question. To provide you with a detailed, step-by-step solution, I'll need clarity and coherence in the problem statement. Let's break down the elements to understand better.
1. Equation:
It appears there’s an equation given: [tex]\( 25 - B = 7 - B \)[/tex].
2. Numbers:
Random numbers like 2, 3, 25, 2 are provided without context.
3. Workers Problem:
There is a scenario involving a teacher, a technician, and possibly another party working together on a task.
For the first equation part:
- To solve [tex]\( 25 - B = 7 - B \)[/tex]:
Subtract [tex]\( B \)[/tex] from both sides:
[tex]\[ 25 - B = 7 - B \][/tex]
The terms [tex]\( B \)[/tex] cancel out:
[tex]\[ 25 = 7 \][/tex]
This statement [tex]\( 25 = 7 \)[/tex] is contradictory, which means there's an error in the equation provided. It would normally be inconsistent.
For the second part of the problem involving the teacher and technician:
- To frame the problem correctly:
Imagine a teacher (T) can do a job in a certain number of hours (U), a technician (Tech) can do the same job in 3 hours, and another party can do it in a given complexity not clearly provided (like [tex]\( 1250^{\circ} \)[/tex]).
Here's a typical workforce problem solved:
If Worker A's rate is [tex]\( \frac{1}{U} \)[/tex] of the job per hour, Worker B’s rate is [tex]\( \frac{1}{3} \)[/tex] of the job per hour, and Worker C's rate [tex]\( \frac{1}{C} \)[/tex] (a formula not clearly provided here).
The combined work rate of these three individuals is:
[tex]\[ \frac{1}{U} + \frac{1}{3} + \frac{1}{C} = \frac{1}{T} \][/tex]
Where [tex]\( T \)[/tex] is the time taken when all work together.
Sorry, a correct, completely coherent equation among unknown constants isn't provided. If you clarify these, I'll provide a detailed step-by-step solution.
