paranteza patrata deschisa ( x + 350 impartit la 5 ) x4 + 6 paranteza patrata inchisa x 2 =612

Answer 1

Răspuns:

Explicație pas cu pas:

[ 123 - 24 × ( 8 : 4 + 96 : x ) ] : 3 = 1

123 - 24 × ( 2 + 96 : x ) = 1 × 3

24 × ( 2 + 96 : x ) = 123 - 3

24 × ( 2+ 96 : x ) = 120

2 + 96 : x = 120 : 24

2 + 96 : x = 5

96 : x = 5 - 2

96 : x = 3

x = 96 : 3

x = 32

__________________________

[ ( x + 350 : 5 ) × 4 + 6 ] × 2 = 612

( x + 70 ) × 4 + 6 = 612 : 2

( x + 70 ) × 4 + 6 = 306

( x + 70 ) × 4 = 306 - 6

x + 70 = 300 : 4

x + 70 = 75

x = 75 - 70

x = 5
