x = daughter's age now
\n" ); document.write( "4x = man's age now {man is 4 times as old as daughter}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 16 = daughter in 16 years
\n" ); document.write( "4x + 16 = man in 16 years\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + 16 = 2(x + 16) {after 16 years, he will be twice as old as her}
\n" ); document.write( "4x + 16 = 2x + 32 {used distributive property}
\n" ); document.write( "4x = 2x + 16 {subtracted 16 from both sides}
\n" ); document.write( "2x = 16 {subtracted 2x from both sides}
\n" ); document.write( "x = 8 {divided both sides by 2}
\n" ); document.write( "4x = 32 {substituted 8, in for x, into 4x}\r
\n" ); document.write( "
