Question

[ 48 + 50 × 100 : (28 : a + 3 × 2) - 14] × [( 50 - 4 × 5 ) + (143 - 4 × 6)] = 42 316
Aflati " a "​

Answer 1

Răspuns:

[48+ 50x100 : (28 :a + 6)-14] x [(50 -20) +(143-24)]= 42 316

[34+ 50 x 100: (28 :a +6)] x (30+ 119)= 42 316

[34 + 50 x 100 :(28 :a + 6)] x 149= 42 316

34 + 50 x 100: (28 : a +6)= 384

50x 100 :( 28 :a +6)= 350

100 :(28 :a + 6)= 7

28 : a + 6= 700

28:a = 694 => a= 694 x 28

a= 19 432
