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
