let x be the girls age and y be her brothers age, then
\n" ); document.write( "x + y = 26
\n" ); document.write( "(x-3) = 4(y-3)
\n" ); document.write( "solve fist equation for x and substitute in second equation
\n" ); document.write( "(26-y-3) = 4y -12
\n" ); document.write( "23-y = 4y -12
\n" ); document.write( "add y to both sides of =, then add 12 to both sides of =
\n" ); document.write( "5y = 35
\n" ); document.write( "y = 7 and x = 19
\n" ); document.write( "The girl is 19 and her brother is 7
