Question

Eight less than four times a number is less than 56. What are the possible values of that number?

Answer 1

Answer: x less-than 12

Explanation:

If we were to word out, eight less than four times a number is less than 56, we get 4x - 8 < 56. Now since we have the equation we simply solve it and replace the lesser sign with an equal sign (Don't worry we will replace it back).

1.) 4x - 8 = 56

2.) 4x - 8 (+ 8) = 56 (+ 8)

3.) 4x = 48

4.) 4x/4 = 48/4

5.) x = 12

6.) x < 12

Now we have the answer, x less than 12 (x<12).
