Question

63-{4+ 5x[8x(10- x:10)]}: 2= 1 ​

Answer 1

Răspuns:

X = 70

Explicație pas cu pas:

63 - { 4 + 5 x [8 x( 10-X : 10)]} : 2 = 1

{4 + 5 x [ 8 x ( 10 - X : 10 )]} : 2 = 63 - 1

{4 + 5 x [ 8 x ( 10 - X : 10 )]} : 2 = 62

4 + 5 x [8 x ( 10 - X : 10)] = 62 x 2

4 + 5 x [ 8 x ( 10 - X : 10)] = 124

5 x [8 x ( 10 - X : 10)]= 124 - 4

5 x [8 x ( 10 - X : 10) = 120

8 x ( 10 - X : 10 ) = 120 : 5

8 x ( 10 - X : 10 ) = 24

10 - X : 10 = 24 : 8

10 - X : 10 = 3

X : 10 = 10 - 3

X : 10 = 7

X = 7 x 10

X = ‘70
