The answer is the additive identity postulate.
Answer:
(2,-3)
Step-by-step explanation:
2x + 2y = -2
3x - 2y = 12
Add the two equations to eliminate y
2x + 2y = -2
3x - 2y = 12
-----------------------
5x = 10
5x/5 = 10/5
x = 2
Now find y
2x+2y = -2
2(2)+2y = -2
4+2y = -2
Subtract 4 from each side
4-4 +2y = -2-4
2y = -6
Divide by 2
2y/2 = -6/2
y = -3
(2,-3)
This is how i got the result, i hope it is correct!
Y would be -5/8 since 1*-5/8 is still -5/8 (identity property.)
Answer: 35/3
Step-by-step explanation:
if you change 2 and 1/3 into an improper fraction it becomes 7/3
then you multiply 7/3 by 5 because their are 5 groups then you get
35/3
