Question

(9*4-7*3)*5+(Y-72:2:3)=96:3

Answer 1

(36-21)*5+(y-36:3)=32
15*5+y-12=32
75-12+y=32
63+y=32
Y=32-63
Y=-31

Answer 2

( 9 × 4 - 7 × 3 ) × 5 + ( Y - 72 : 2 : 3 ) = 96 : 3

( 36 - 21 ) × 5 + ( Y - 36 : 3) = 32

15 × 5 + ( Y - 12 ) = 32

75 + ( Y - 12) = 32

y - 12 = 32 - 75

y - 12 = - 43

y = - 43 + ( - 12)

y = - 55

Daca dupa prima paranteza semnul este ,, : 5 " atunci y va fi:

( 36 - 21) : 5 + ( y - 12 ) = 32

15 : 5 + ( y - 12) = 32

3 + ( y - 12) = 32

y - 12 = 32 - 3

y = 29 + 12

y = 41
