Answer 1

9 *(1+2x)/3-5x=8
3(1+2x)-5x=8
3+6x-5x=8
x=5

Answer 2

9($\frac{1}{3} + \frac{2}{3}x)-5x=8$=>$\frac{9}{3} + \frac{18}{3}*x-5x=8\ \textless \ =\ \textgreater \ 3+6x-5x=8\ \textless \ =\ \textgreater \ 3+x=8 =\ \textgreater$$=\ \textgreater \ x= 5$
Deci, x=5.
Am ajuns imediat la 3 si 6x , deoarece am impartit 9 la 3 si 18x la 3.
