Question

Which of the following is the same as $x-999\le 101$?

• A. $x\ge 1100$
• B. $x>1100$
• C. $1100\ge x$
• D. $1100\le x$

Answer 1

The correct option is C $1100\ge x$

Clearly, we can use the basic arithmetic operations to get rid of the -999 from the left-hand side by adding +999 to both the sides.
$\Rightarrow x-999+999\le 101+999$
$\Rightarrow x\le 1100$ or $1100\ge x$
