Question

(X-5 totul supra 3 )- 1 = (X +1 totul supra 2 )-4

Ajutor !!!!!!

Answer 1

Salut,

(x-5/3)-1=(x+1/2)-4

2(x-5)-6=3(x+1)-24

2x-10-6=3x+3-24

2x-16=3x-21

2x-3x=-21+16

-x=-5

x=5

Bafta!

Answer 2

( x - 5) / 3 - 1 = ( x + 1 ) / 2 - 4

( x - 5 - 3 ) / 3 = ( x + 1 - 8 ) / 2

( x - 8 ) / 3 = ( x - 7 ) / 2

2 ( x - 8 ) = 3 ( x - 7 ) → produsul mezilor = produsul extremilor

2 x - 16 = 3 x - 21

3 x - 2 x = 21 - 16

x = 5
