2x + 1 < (3x + 2)/x + 2
solutio:
we remove bracket
=2x + 1 > 3x + 2/x + 2
collection of like terms
=2x+3x>2+1/x+2
=5x+3/x+2

2x+1<(3x+2)/x+2
firstly finding the L.C.M
and the L.C.M is x+2
therefore
2x+1(x+2)<3x+2
open the bracket
2x2 + 4x + x + 2 < 3x + 2
collect like terms
=2x2 + 4x + x - 3x < 2-2
=2x2 + 2x < 0
=2(x2 + x) < 0
firstly finding the L.C.M
and the L.C.M is x+2
therefore
2x+1(x+2)<3x+2
open the bracket
2x2 + 4x + x + 2 < 3x + 2

I think I made a mistake
2x+1<(3x+2)/x+2
L.C.M = x+2
:.
2x+1(x+2)<3x+2
2x2 + 4x + x + 2 < 3x + 2
CLT
=2x^2 + 4x + x - 3x < 2-2
=2x^2 + 2x < 0
Then break it down by dividing 2x^2 + 2x by 2 which is
2x^2+2x/2
=x^2+x < 0
=x>-1 Answer
2x+1<(3x+2)/x+2
L.C.M = x+2
:.
2x+1(x+2)<3x+2
2x2 + 4x + x + 2 < 3x + 2
CLT
=2x^2 + 4x + x - 3x < 2-2
=2x^2 + 2x < 0
Then break it down by dividing 2x^2 + 2x by 2 which is
=x^2+x < 0
=x>-1 Answer
