The difference between a number and 12 is 20

Answer 1

Let x be the number

The difference between a number and 12 is 20

x - 12 = 20

Answer 2

Since no number is given, we can use X.

X-12= 20

Since we are solving for X then we have to separate it from the rest of the equation.

To do that, we have to get rid of the 12 beside the X. When we move the 12, it becomes a positive 12.

The equation now reads:

X=20+12

Therefore X = 32

Proof: (32-12= 20)

Answer 3

This sentence must be translated from English to math symbols. Difference is the answer to a subtraction problem. A number is represented by n. Thus the sentence is translated n-12 = 20. To solve this equation one must add 12 to each side and find n = 20 + 12 or 32.
