Question

5) Resolva a Inequação do 1º grau x/3 - (x+1)/2 <(1 - x)/4​

Answer 1

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

$\frac{4x}{12}-\frac{6(x+1)}{12}<\frac{3(1-x)}{12}$

$\frac{4x}{12}-\frac{6x+6}{12}<\frac{3-3x}{12}$

$\frac{4x-(6x+6)}{12}<\frac{3-3x}{12}$

$\frac{4x-6x-6}{12}<\frac{3-3x}{12}$

$4x-6x-6<3-3x$

$4x-6x+3x<3+6$

$x<9$
