Right now, John is 5 times older than Nick. Let n represent Nick's age and J for John's age.
\n" ); document.write( "The equation would be 5n=j\r
\n" ); document.write( "\n" ); document.write( "In 15 years, John will be 3 times older than Nick. This would then be: j+15=3(n+15)\r
\n" ); document.write( "\n" ); document.write( "Using distributive property: j+15=3n+45
\n" ); document.write( "Subtract both sides by 15 to get j=3n+30\r
\n" ); document.write( "\n" ); document.write( "j also equals 5n, therefore 3n+30=5n\r
\n" ); document.write( "\n" ); document.write( "Subtract both sides by 3n to get 2n=30\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 2 to get n=15
\n" ); document.write( "Right now, Nick is 15 years old, multiply by 5 to get John's age, which is 75.\r
\n" ); document.write( "\n" ); document.write( "CHECK:
\n" ); document.write( "If Nick is 15 right now, John is 75.
\n" ); document.write( "In 15 years, Nick will be 30 and John will be 90.
\n" ); document.write( "30*3 is 90, so our answer is correct.\r
\n" ); document.write( "\n" ); document.write( "John is 75 years old. \n" ); document.write( "

\n" );
