Question

B) The difference between 64 and a number is equal to 48​

Answer 1

16

64 - x = 48
16 - x = 0
16 = x

Answer 2

Explanation:

I am going to begin by calling the number k.

The difference between 64 and k is 64 - k.

Since it's also equal to 48, we just write = 48:

64 - k = 48

-k = 48 - 64

-k = -16

k = 16

Answer :

k = 16
