there are no like terms in this so thats your answer
Step-by-step explanation:
Answer:
tan p = 5/12.
tan p = cot r.
Step-by-step explanation:
RQ = √(13^2 - 12^2)
= √25
= 5.
tan p = opposite side / adjacent side = 5/12.
cot r = adjacent side / opposite side = 5/12.
tan p = cot r.
Question 1

Distributing 2 on 5y -2, we will get

But student get

So the student make an error in step 2 .
Second question

To get rid of y, we have to multiply first equation by -8 and add the resultant equation with equation Q .
