The inequality is
.
Apply subtraction property of inequality: Subtract 6 from each side.
\
Apply commutative property of addition: a + b = b + a.
\
(Apply additive inverse property:
)
(Apply additive identity property:
)
(Subtract:
)
(Multiply each side by negative one and flip the symbol)
(Product of two same signs is positive)
Check:
\To check, substitute three different values for h into the original inequality
: 14, a number less than 14, and greater than 14.
Let three values are
.
If
then
(This is true)
If
then
(This is false)
If
then
(This is false).
