Answer:
its 10...
Step-by-step explanation:
Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
19x-53 / x^2 + x + 2
You want to put a - ( 19 x / x^2 + x + 2 - 53/x^2 +x +2)
