Answer

a) $12 - x = -45$ b) $12x = -45$ c) $x - 10 = 2x$

Work Step by Step

a) Since the difference of 12 and the number $x$ is -45, we have, $12 - x = -45$. b) Since the product of 12 and the number $x$ is -45, we have $12x = -45$. c) Since the number $x$ less 10 is twice the number itself, we have, $x - 10 = 2x$.
