From the SAS inequality theorem , .
(SAS inequality)
(Add 7 to each side)
(Subtract x from each side)
(Divide each side by 2)
Since the measure of any side is always greater than zero.
\ (Add 7 to each side)
(Divide each side by 3)
The two inequalities can be written as the compound inequality
The inequality for the possible values of x is .
