Answer:
23 + x = 40
Step-by-step explanation:
Hi,
23 is the total amount your friend has. 23 + the total amount you have is equal to 40. Since we don't know how much you have, we can write x. Therefore, 23 + x = 40 would be correct.
Hope this helps :)
Answer:
40 - 23 = x
40 - x = 23
x + 23 = 40
Step-by-step explanation:
You can get the sum through either addition or subtraction.
x = 17 (just in case)
