Answer:

52

Explanation:

We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:


3x + 7 = 163

We want to isolate the variable, so subtract 7 from both sides. This gives us:


3x = 156

Finally, we divide both sides by 3, giving:


x=52

So the teacher is 52 years old.

Hope this helps!
