[(a×4-8):4+38]:3=17

[(a×4-8):4+38]=17×3

[(a×4-8):4+38]=51

(a×4-8):4=51-38

(a×4-8):4=13

a×4-8=13×4

a×4-8=52

a×4=52+8

a×4=60

a=60:4

a=15

Answer 2

Explicație pas cu pas:

[(a⨯4-32:4):4+38]:3 = 17

[(a⨯4-8):4+38]:3 = 17

(a⨯4-8):4+38 = 17⨯3 = 51

(a⨯4-8):4 = 51-38 = 13

a⨯4-8 = 13⨯4 = 52

a⨯4 = 52+8 = 60

a = 60:4

a = 15
