Rezolvalti exercițiul 5 punctul c.

Answer 1

3x+3*$\frac{3}{2}$ + 2x = 7x +$\frac{3}{2}$
5x+$\frac{9}{2}$ = 7x +  $\frac{3}{2}$
$\frac{9}{2}$= 7x - 5x + $\frac{3}{2}$
$\frac{9}{2}$= 2x + $\frac{3}{2}$
2x= $\frac{9}{2}$-$\frac{3}{2}$
2x=$\frac{6}{2}$
x= $\frac{6}{2}$: 2
x= $\frac{6}{2}$* $\frac{1}{2}$
x=$\frac{6}{4}$
