Given the equation:

A number plus 12 is 36.

Find the number.

Solution:

In order to solve the equation, we must first equate the given as,

x = missing number

x + 12 = 36

Solve for x.

Start first by transposing 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 = 36

x = 36 - 12

x = 24

Final answer:

x = 24
