Answer:
I believe the answer is D.
System of equations:
x + y = 23
x - y = 7
Add them together
2x = 30
x = 15
Now plug 15 into one of the equations:
15 + y = 23
y = 8
your two numbers are 15 and 8
Answer: -4
Step-by-step explanation:
-8x+4=36
-8x=36-4
-8x=32
-8x/-8=32/-8
x= -4
P=2(k+w)
p=2k+2w
(subtract 2k from both sides)
p-2k=2w
(divide 2 from both sides)
p/2-k=w
w=p/2-k thats what i got. hope this helps love! :)
