Question

Va rog frumos!!
Rezolva (corect) ecuatiile:
4x+2/5 = 1-x/2

Answer 1

Răspuns:

¹⁰⁾4x+²⁾2/5=¹⁰⁾1-⁵⁾x/2

40x+4=10-5x

40x+5x=10-4

45x=6

x=6/45=>x=2/15

Answer 2

Răspuns:

modul de a scrie cerinta lasa loc de interpretari de aceea iti voi rezolva in 2 moduri, ramanand ca tu sa alegi varianta corecta

$\frac{4x+2}{5}=\frac{1-x}{2}=>8x+4=5-5x=>8x+5x=5-4=>13x=1=>\\\\x=\frac{1}{13}$

$4x+\frac{2}{5}=1-\frac{x}{2}=>40x+4=10-5x=>40x+5x=10-4=>45x=6=>\\ \\x=\frac{6}{45}=\frac{2}{15}$
