Question

5x[128:2x4+(x•y-41)•3=2015 x,y=? x

Answer 1

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

Răspuns:

1335???

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
