$x<3/2$ or $x<1.5$

Given: $3x+3<x+6$ .

Subtract $x$ from both sides.

$3x+3-x<color(red)cancelcolor(black)x+6-color(red)cancelcolor(black)x$

$2x+3<6$

Subtract $3$ from both sides.

$2x+color(red)cancelcolor(black)3-color(red)cancelcolor(black)3<6-3$

$2x<3$

Divide by $2$ to get $x$ .

$(color(red)cancelcolor(black)2x)/(color(red)cancelcolor(black)2)<3/2$

$x<3/2=1.5$
