Answer 2

C) r + s + x = t + y

Step-by-step explanation:

Given options are

A) r + s - x = y - t

B) r + s - t = x + y

C) r + s + x = t + y

D) r + s + t = x - y

Verifying each option we can get the answer

A) r + s - x = y - t

If we subtract the given equations,

r + s - x = t - y ---(1)--- This is not the correct option.

B) r + s - t = x + y

From (1), r + s - x = t - y

r + s - t = x - y Since, this doesn't match the option its incorrect.

C) r + s + x = t + y

Adding two equation gives,

r + s + x = t + y

As, this matches option C it is correct answer.

D) r + s + t = x - y

This is also incorrect because we can see through the given equation that r + s + t is not possible.
