8 less than four times a number is 12 determine the number
blondinia [14]

Answer:

5

Step-by-step explanation:

With this one, you need to work backwards.

First, you want to add 8 to 12, as addition is opposite subtraction. This gives you 20. Then, you want to divide 20 by 4, as division is the opposite of multiplication. That gives you 5, which is your answer.

It works the other way round if you were to check it. 5 x 4 is 20, 20 - 8 is 12.
