Answer:
it's 20
Step-by-step explanation:
I just had the same question and I got it right it's 20.
<u>Answer:</u>
The correct answer option is (21, 2).
<u>Step-by-step explanation:</u>
We are given the following two equations and we are to find the solution to this system of equations:
--- (1)
--- (2)
Since the left hand side of the both the equation is equal so we can equate the right hand sides of these equations equal to each other.

x = 21
Substituting this value of x in (2) to find y:
y = 2
