Answer 1

Răspuns:

Explicație pas cu pas:

a)  2x + 3x = 35

     5x = 35

     x = 35 : 5

     x = 7

_______________

b)

5x - 3x = 46

2x = 46

x = 46 : 2

x = 23

___________

c)

6x + 2x + 4x = 72

12x = 72

x = 72 : 12

x = 6

Answer 2

Salut!

E mai simplu,decât crezi:

a) 2x+3x=35

5x=35⇒x=35:5⇒x=7

b) 5x-3x=46

2x=46⇒x=46:2⇒x=23

c) 6x+2x+4x=72

12x=72⇒x=72:2⇒x=6

Succes!
