Question 32986
5(2+x)> -4(x+3)
10 + 5x > -4x -12
10 + 5x +4x + 12 > 0
22 + 7x > 0
7x > -22
x > -22/7
as this is the value of pi,we get
{{{ x > -pi) }}}
<P>
Interval notation can only be applied if you specify interval of which set?
Complex,Reals,Integers...? That is simple enough once you have the basic inequality,as above.

Hope this helps,
