Question

PLSSS AJUTOOR LA MATEEEEE ​

Answer 1

b) [( 2x + 108) - (21 + 23)] : 2 = 232
(2x + 108 - 44) : 2 = 232
(2x + 64) = 232 : 2
2x + 64 = 116
2x = 116-64
2x = 52
x = 26

Answer 2

Răspuns:

b) [(2x + 108 ) - ( 21 + 23 )] : 2 = 232

[ ( 2x + 108 ) - ( 21 + 23 ) ] = 232 • 2

[ ( 2x + 108 ) - ( 21 + 23 ) ] = 464

( 2x + 108 ) - 44 = 464

( 2x + 108 ) = 464 + 44

2x + 108 = 508

2x = 508 - 108

2x = 400

x = 400 : 2

x = 200
