let andre′s money be= x  let Bob′s money be=y  x−20=y+20⇒(1)  2(y−22)=x+22⇒(2)  x−y=40  x−2y=−66  y=106  x=40+106  x=146  Andre has 146  Bob has 106
$${let}\:{andre}'{s}\:{money}\:{be}=\:{x} \\ $$$${let}\:{Bob}'{s}\:{money}\:{be}={y} \\ $$$${x}−\mathrm{20}={y}+\mathrm{20}\Rightarrow\left(\mathrm{1}\right) \\ $$$$\mathrm{2}\left({y}−\mathrm{22}\right)={x}+\mathrm{22}\Rightarrow\left(\mathrm{2}\right) \\ $$$${x}−{y}=\mathrm{40} \\ $$$${x}−\mathrm{2}{y}=−\mathrm{66} \\ $$$${y}=\mathrm{106} \\ $$$${x}=\mathrm{40}+\mathrm{106} \\ $$$${x}=\mathrm{146} \\ $$$${Andre}\:{has}\:\mathrm{146} \\ $$$${Bob}\:{has}\:\mathrm{106} \\ $$$$ \\ $$$$ \\ $$
