Aflati x.Dau coroana celui mai bun răspuns. ​

Answer 1

Răspuns:  x = 3

Explicație pas cu pas:

(3/4) / x = ( 3/4) : x = ( 3/4) × ( 1/x) = 3/4x

4/(2/3) = 4 : (2/3) = 4 × ( 3/2) = 12/2 = 6

====================================

3/4x + 6 = 25/4

3/4x = 25/4 - ⁴⁾6

3/4x = 25/4 - 24/4

3/(4x) = 1/4 ⇒ 4x × 1 = 3 × 4  → produsul mezilor = produsul extremilor

4 x = 12

x = 12 : 4

x = 3

----------------------------------------------------------------------

verific:

3/4 : 3 = (3/4 ) × ( 1/3) = 1/4

1/4 + 6 = 1/4 + 24/4 = 25/4 √
