How do you solve compound inequalities #4x<16# or #12x>144#?

1 Answer

Answer:

#{x|x<4 or x>12}#

Explanation:

we'll look at #4x<16#: let's devide it by 4 and we obtain: #x<4#
let's look at the other one: #12x>144#. we divide it by 12 and obtain #x>12#. so we have that #x<4# , #x>12#, which means: that x must be less than 4, or x must bigger than 12 i.e: #{x|x<4 or x>12}#
