RESOLUCIÓN :

$x/5=16 x = 5.16 = 80 ----------------------- 2x-9=x+18 2x-x = 18+9 x =27 ------------------------- 9x+9=900 9x = 900-9 9x =891 x=891/9 x=99 ------------------------------- 1/4 x-2=250 1/4 x -2 +2 =250+2 1/4 x =252 x=252.4 x=1008 ----------------------- x/3-11=x-233 x/3 -11+11 = x-233+11 x/3 =x-222 x/3 -x = x-222-x -2/3 x = -222 Multiplicar .3 -2x =-666 x= -666/-2 x=333 --------------------- x+5=2x-80 80+5 =2x-x 85=x$
