x = Mary's age
\n" ); document.write( "x + 5 = George's age\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + x + 5 = 43 {sum of ages is 43}
\n" ); document.write( "2x + 5 = 43 {combined like terms}
\n" ); document.write( "2x = 38 {subtracted 5 from each side}
\n" ); document.write( "x = 19 {divided each side by 2}
\n" ); document.write( "x + 5 = 24 {substituted 19, in for x, into x + 5}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Mary is 19
