xxxx but with the following two xxxxx xx xxxxxxxxx If you multiply xx xxxxxx xxxx xxxxx xx a xxxxxxxx xxxxxxx xxxx the inequality sign xx xxxxxxxx (> becomes). xxxxxx and subtracting numbers have no effect xx xxx direction of the inequality. xxxxx xx you have a xxxx equals' sign, then it is xxxxxxxxxx by the multiplication. xxx xxxx is xxxx xx xxx xxxx the xxxxxxxxxx of both sides. Example: xxxx xxx xxxxxxxxx 1/x = xx xxxx xxx reciprocal xxx x x 1/2.
With the xxxxxxxxxx x / x 1 x 2. You could also xxxxx xx by xxxxxxxxxxx both sides by xx then dividing both xxxxx xx 2, xxx xxx 2 2.

xxxx xxx inequality 1 x x 1 x xx You xxxxx also xxxxx xx by xxxxxxxxxxx both sides by x, then xxxxxxxx both xxxxx xx 2, and xxx 2 2. Another example: 3 x x > xx xxxxxxxx x from xxxx xxxxxx -x > 4. Multiply both sides by -1: x 7 x xx then xxxxxxxx 7 xxxx both sides: xx > xx xxxxx means xxx xxxx xx x < xx
