Question

resolva as inequações, com u=q

a. 2x+4>3
b. 3x+2>x-1
c. -x/2 +1> -2

Answer 1

$2x + 4 > 3 \\ 2x > 3 - 4 \\ x > - \frac{1}{2}$



$3x + 2 > x - 1 \\ 3x-x>-1 -2 \\ 2x >-3 \\ x> - \frac{3}{2}$



$- \frac{x}{2} + 1 > - 2 \\ \\ - \frac{x + 2}{2}> -2 \\ \\ - x + 2 > -4 \\ \\ -x > -4 -2 \\ \\ x > \frac{6}{1}$
