Question

2x+4y/4y=18/8 va rog na puteti ajuta ca sa imi pot da seama

Answer 1

2x+$\frac{4y}{4y}$ = $\frac{18}{8}$
2x +$\frac{4y}{4y}$ ( devine 1 ca este fix un intreg) = 2x+1=$\frac{18}{8}$ = 2x+1-$\frac{18}{8}$ = 2x+2$\frac{2}{8}$= 2x+$\frac{18}{8}$ = $\frac{2}{1}$ : $\frac{18}{8}$ = $\frac{2}{1}$ × $\frac{8}{18}$ = $\frac{16}{18}$ 

Sper ca te-am ajutat :D !

Answer 2

2(x+2y)/4y=18/8
(x+2y)/2y=9/4
x/2y+1=9/4
x/2y=9/4-1
x/2y=5/4
x=5
y=2
Vf.2(5+4)/8=18/8
