Hey!❄
5×[128÷2×4 + (x×y - 41)×3] + 2015
[64×4 + (x×y - 41)×3] = 2015÷5
256 + (x×y - 41)×3 = 403
(x×y - 41)×3 = 403 - 256
(x×y - 41)×3 = 147
x×y - 41 = 403÷3
x×y - 41 = 49
x×y = 49 + 41
x×y = 90
____________________________
x = 1, y = 90
x = 2, y = 45
x = 3, y = 30
x = 5, y = 18
x = 9, y = 10
x = 10, y = 9
x = 18, y = 5
x = 30, y = 3
x = 45, y = 2
x = 90, y = 1
Sper ca te-am ajutat!☃

Explicație pas cu pas:
5×[128÷2×4+(x•y-41)×3]=2015
5×[128÷2×4+3x•3y-123]=2015
5×[64×4+3x•3y-123]=2015
5×[256+3x•3y-123]=2015
5×[133+3x•3y]=2015
5×[133+3(x•y)]=2015
665+15(x•y)=2015
680+x•y=2015
x•y=2015-680=1335
