sol:
\n" ); document.write( "let Wang's age be x
\n" ); document.write( "Mary is twice Wnag's=2*x
\n" ); document.write( "kat is 2 years younger the wang=x-2
\n" ); document.write( "according to the problem
\n" ); document.write( "sum of their ages=46
\n" ); document.write( "x+2x+x-2=46
\n" ); document.write( "4x-2=46
\n" ); document.write( "adding 2 on both sides
\n" ); document.write( "4x-2+2=46+2
\n" ); document.write( "4x=48
\n" ); document.write( "dividing by 4 on both sides
\n" ); document.write( "4x/4=48/4
\n" ); document.write( "x=12
\n" ); document.write( "Wang's age=12 years
\n" ); document.write( "Mary age=2*Wang's age=2*12=24 years
\n" ); document.write( "Kat age=Wang's age-2=12-2=10 years
\n" ); document.write( "check:
\n" ); document.write( "sum of their ages=46
\n" ); document.write( "Wang's age+Mary age+Kat age=12+24+10=46
\n" ); document.write( "L.H.S=R.H.S\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
