Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)

Answer:
0
Step-by-step explanation:
Cancel out x-y to x^2-Y^2 and you get x+y-x-y which is 0

-8n-24+28=-5n-5
</span>-8n+4=-5n-5
-8n+4-4=-5n-5-4
-8n=-5n-9
-8n+5n=-5n+5n-9
-3n=-9
-3n/-3=-9/-3
n=3
n=3 is the correct answer
