Answer:
Go on Khan academy <3
Step-by-step explanation:
Step-by-step explanation:
2x - 5 = y - 5
2x = y
x = y/2
y - 3 = x + 1
Substitute the value of x here,
y - 3 = 
y - 3 = 
2y - 6 = y + 2
y = 8
Now, x = 8/2
x = 4
So, go for D part, it is the correct answer.
Good Night/Day !

I think their correct but hopefully they helped!
Hi there!
Here are the important information we know:
Earth : 365 days
Mars : 687 days
In order to find out how many more days (d) Mars takes than Earth to orbit the sun, you'll need to subtract 365 from 687, so your equation would look like this:
687 - 365 = d
Now to solve this equation :
687 - 365 = d
322 = d
This means that Mars takes 322 days more than Earth to orbit the sun.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
4x = y
Step-by-step explanation:
If y is 36 and x is 9, you know 9 x 4 = 36. So it would be 4x = y
