Add 9 to 14 . And then the answer will equal x
texaschic101
14 = x - 9...this is an open sentence...because we do not know if this is a true or a false statement...we do not know what the variable is.

4 - 15 = 22 - 33
-11 = -11.....this is true

-7(5-9) = 19 - 3(-3)
-7(-4) = 19 + 9
28 = 28 ....this is true
