Question

(X x 0,25 + 1999 )x 20 =(50+1999)x20

Answer 1

( X x 0,25 + 1999 ) x 20 = ( 50 + 1999 ) x 20

( X x 0,25 + 1999 ) x 20 = 2049 x 20

( X x 0,25 + 1999 ) x 20 = 40 980

X x 0,25 + 1999 = 40 980 : 20 

X x 0,25 + 1999 = 2049

X x 0,25 = 2049 - 1999

X x 0,25 = 50

       X = 50 : 0,25

       X = 200

Answer 2

=>X*0,25=50 =>x=200

Answer 3

(X x 0,25 + 1999 )x 20 =(50+1999)x20

=> X x 0,25 + 1999 = 50 + 1999

=> X x 0,25 = 50

=> X = 50 : 0,25

=> X = 200

Answer 4

X=200

Answer 5

( X x 0,25 + 1999 ) x 20 = ( 50 + 1999 ) x 20

( X x 0,25 + 1999 ) x 20 = 2049 x 20

( X x 0,25 + 1999 ) x 20 = 40 980

X x 0,25 + 1999 = 40 980 : 20 

X x 0,25 + 1999 = 2049

X x 0,25 = 2049 - 1999

X x 0,25 = 50

       X = 50 : 0,25

       X = 200
