Question

14 + {4 x [28 + (a + 2): 6] – 5} : 5 = 37​

Answer 1

Răspuns:

a=10

Explicație pas cu pas:

14+{4*[28+(a+2):6]-5}:5=37

{4*[28+(a+2):6]-5}:5=37-14

{4*[28+(a+2):6]-5}:5=23 | *5

4*[28+(a+2):6]-5=115

4*[28+(a+2):6]=115+5

4*[28+(a+2):6]=120 | :4

28+(a+2):6=30

(a+2):6=30-28

(a+2):6=2 | *6

a+2=12

a=12-2

a=10
