Answer 1

Răspuns:

Explicație pas cu pas:

234 + [( 88 : 4 + j ) - 78 : 6 ] x 23 = 809

[( 22 + j ) - 78 : 6 ] x 23 = 809 - 234

[ ( 22 + j ) - 78 : 6 ] x 23 = 575

[ ( 22 + j ) - 78 : 6 ] = 575 : 23

[ ( 22 + j ) - 78 : 6 ] = 25

( 22+ j ) - 13 = 25

22 + j = 25+13

22 + j = 38

j = 38-22

j = 16

Answer 2

234 + [ ( 88 : 4 + j ) - 78 : 6 ] × 23 = 809

234 + [ ( 22 + j ) - 13 ] × 23 = 809

[ ( 22 + j ) - 13 ] × 23 = 809 - 234

[ ( 22 + j ) - 13 ] × 23 = 575

( 22 + j ) - 13 = 575 : 23

( 22 + j ) - 13 = 25

22 + j = 25 + 13

22 + j = 38

j = 38 - 22

j = 16
