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

x less-than 12

x greater-than 16

Answer 2

For this case we can algebraically rewrite the expression given as:

$8-4x$

Where:

x: Represents the unknown number

Subtracting 8 from both sides of the inequality we have:

$-4x$

Dividing between 4 on both sides of the inequality:

$-x$

We multiply by -1 on both sides taking into account that the sense of inequality changes:

$x> -12$

ANswer:

$x> -12$
