Question

2x+1/4x+3=1/3 aflati x

Answer 1

2x+1/4x+3=1/3

(4x+3).1=3(2x+1)

4x+3=6x+3

-2x=0

x= 0/-2

x=0

Answer 2

Răspuns:

Explicație pas cu pas:

( 2x +1)/(4x+3) = 1/3 → proportie

3(2x+1) = 4 x + 3 → produsul mezilor = produsul extremilor

6 x + 3 = 4 x + 3

6 x - 4 x = 3 - 3

2 x = 0

x = 0/2

x = 0
