Question

3x<(2+1) ; x+1/2>-1 ; 2-x/2>1/3 ; -3x<5/3-x !! Dau coroana pentru solutile inecuatiilor !!

Answer 1

3x<(2+1)
3x<3 |:3
x<1

x+1/2>-1
x > -1/2-1/1 ( aducem la acelasi numitor)
x> -1/2-2/2
x> - 3/2

2-x/2>1/3
-x/2> -2/1+1/3 ( aducem la acelaşi numitor)
-x/2> -6/3+1/3
-x/2> -5/3

-3x<5/3-x
-3x+x< 5/3
-2x< 5/3 |:(-2)
x< 5/3•(-1/2)= -5/6
x< -5/6
