Answer 1

Răspuns:

39 / 5

Explicație pas cu pas:

Bună! ʕ•́ᴥ•̀ʔっ

3 × { 10 + 2 × [ 40 - 2 × ( 27 - 4 × 3 ) ] } - 5x = 51

3 × { 10 + 2 × [ 40 - 2 × ( 27 - 12 ) ] } - 5x = 51

3 × { 10 + 2 × [ 40 - 2 × 15 ] } - 5x = 51

3 × { 10 + 2 × [ 40 - 30 ] } - 5x = 51

3 × { 10 + 2 × 10 } - 5x = 51

3 × ( 10 + 20 ) - 5x = 51

30 + 60 - 5x = 51

90 - 5x = 51

- 5x = 51 - 90

- 5x = - 39

5x = 39

x = 39 / 5
