Sam's age = $\"x\"$
\n" ); document.write( "his brother's age = $\"x+%2B+7\"$
\n" ); document.write( "mother's age = $\"3x-4\"$
\n" ); document.write( " $\"x%2B%28x%2B7%29%2B%283x-4%29=63\"$
\n" ); document.write( " $\"x%2Bx%2B7%2B3x-4=63\"$
\n" ); document.write( " $\"5x%2B7-4=63\"$
\n" ); document.write( " $\"5x%2B3=63\"$
\n" ); document.write( " $\"5x=63-3\"$
\n" ); document.write( " $\"x=60%2F5\"$
\n" ); document.write( " $\"x=12\"$
\n" ); document.write( "Sam's age = $\"x\"$ = $\"12\"$
\n" ); document.write( "his brother's age = $\"x+%2B+7\"$ = $\"12%2B7\"$ = $\"19\"$
\n" ); document.write( "mother's age = $\"3x-4\"$ = $\"3%2812%29-4\"$ = $\"36-4\"$ = $\"32\"$ \n" ); document.write( "
