1900-X×[6471:9-(3×5×10+25)×4)=1083

1900-X*[719-(150+25)*4]=1083

1900-X*(719-175*4)=1083

1900-X*(719-700)=1083

1900-X*19=1083

X*19=1900-1083

X*19=817

X=817÷19

X=43

1900-43*[6471:9-(3*5*10+25)*4]=

1900-43×[719-(150+25)*4]=

1900-43*(719-175*4)=

1900-43*(719-700)=

1900-43*19=

1900-817=1083
