Question

Aflati nr natural x stiind ca 3•(2x+1)-1=32

Answer 1

Răspuns:

Explicație pas cu pas:

3×( 2x + 1 ) - 1 = 32

6x + 3 - 1 = 32

6x + 3 = 32 + 1

6x + 3 = 33

6x = 33 - 3

6x = 30

x = 30 : 6

x = 5

Answer 2

Răspuns:

3×(2x+1)= 32+1

3×(2x+1)= 33

2x+1= 33:3

2x+1=11

2×x=11-1

2×x=10

x=10:2

x=5
