904+10y+750+x+100z+86=1000w+387  x+10y+100z+1353=1000w  x+3=10 ⇒ x=7  10y+100z+1360=1000w  y+6=10 ⇒ y=4  100z+1400=1000w  z+4=10 ⇒ z=6  2000=1000w ⇒ w=2  x+y+z+w=19
$$\mathrm{904}+\mathrm{10}{y}+\mathrm{750}+{x}+\mathrm{100}{z}+\mathrm{86}=\mathrm{1000}{w}+\mathrm{387} \\ $$$${x}+\mathrm{10}{y}+\mathrm{100}{z}+\mathrm{1353}=\mathrm{1000}{w} \\ $$$${x}+\mathrm{3}=\mathrm{10}\:\Rightarrow\:{x}=\mathrm{7} \\ $$$$\mathrm{10}{y}+\mathrm{100}{z}+\mathrm{1360}=\mathrm{1000}{w} \\ $$$${y}+\mathrm{6}=\mathrm{10}\:\Rightarrow\:{y}=\mathrm{4} \\ $$$$\mathrm{100}{z}+\mathrm{1400}=\mathrm{1000}{w} \\ $$$${z}+\mathrm{4}=\mathrm{10}\:\Rightarrow\:{z}=\mathrm{6} \\ $$$$\mathrm{2000}=\mathrm{1000}{w}\:\Rightarrow\:{w}=\mathrm{2} \\ $$$${x}+{y}+{z}+{w}=\mathrm{19} \\ $$

why x+3=10?
$${why}\:{x}+\mathrm{3}=\mathrm{10}? \\ $$

because 1353 has to get 1000w  1353+zyx=1000w  1353   ^(  ) zyx  ===  w000

because 4 + X + 6 = 17
$$\boldsymbol{{because}}\:\mathrm{4}\:+\:\boldsymbol{{X}}\:+\:\mathrm{6}\:=\:\mathrm{17} \\ $$
