Given the numerical statement:
The difference between a number and 12 is 20.
Solution:
The given numerical statement can be written in the form.
x - 12 = 20
In order to determine the value of the number, we simply needed to transpose -12 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
x - 12 = 20
x = 20 + 12
x = 32
Check:
32 - 12 = 20
20 = 20
Final answer:
x = 32
