Question

3/2x -4/5<1 repedeeeeeeeeee

Answer 1

3/2x -4/5<1 3/2x-1<4/5 (3-2x)/2x<4/5 3-2x<4/5*2x 3-2x<8x/5 5*(3-2x)<8x 15-10x<8x 15<18x /:3 5<6x => 5/6<x 3/(2*5/6)-4/5<1 se simplifica si ramane 3/(5/3)-4/5<1 Iar acum inmultim cu inversa si o sa am 3/1*3/5-4/5<1 de aici 9/5-4/5<1 au aceasi numitor (9-4)/5<1 => 5/5<1 => 1<1 nu este adevarat pentru ca 1=1
