Question

X + 5 . 2 - ( 32 + 16 . 3 : 6 - 15 ) = 0 

X - 6 : 2 - ( 48 - 24 ) : 2 :6 - 3 = 0

Answer 1

  x + 5 . 2 - ( 32 + 16 . 3 : 6 - 15 ) = 0

  x + 10 - ( 32 + 8 - 15 ) = 0

  x + 10 - 25 = 0

  x - 15 = 0

  x = 15

  x - 6 : 2 - ( 48 - 24 ) : 2 : 6 - 3 = 0

  x - 3 - 24 : 2 : 6 - 3 = 0

  x - 3 - 2 = 0

  x - 5 = 0

  x = 5 

Answer 2

x + 5 . 2- (32+48:6-15)=0

x+5.2-(32+8-15)=0

x+5.2-25=0

x+10=0+25=25

x=25-10

x=15
