Answer 1

Respuesta:

a 4-2x < 5 -4x

$4-2x-4<5-4x-4\\\\-2x<-4x+1\\\\-2x+4x<-4x+1+4x\\\\2x<1\\\\\frac{2x}{2}<\frac{1}{2}\\\\x<\frac{1}{2}$

b 5x-7 < 3x -x-1

$5x-7+7<2x-1+7\\\\5x<2x+6\\\\5x-2x<2x+6-2x\\\\3x<6\\\\\frac{3x}{3}<\frac{6}{3}\\\\x<2$

c x+5_4 +x-3_2> 5

$x+x+5_4-3_2>5\\\\2x+5_4-3_2>5\\\\2x+5_4-3_2-\left(5_4-3_2\right)>5-\left(5_4-3_2\right)\\\\2x>5-5_4+3_2\\\\\frac{2x}{2}>\frac{5}{2}-\frac{5_4}{2}+\frac{3_2}{2}\\\\x>\frac{5-5_4+3_2}{2}$
