Andy is 5 years older than Chris in 3 years the sum of their ages will be 35. what are their ages\r
\n" ); document.write( "\n" ); document.write( "Algebraically:
\n" ); document.write( "Chris' age: x
\n" ); document.write( "Andy's age: x+5\r
\n" ); document.write( "\n" ); document.write( "In three years, both will be three years older so then:\r
\n" ); document.write( "\n" ); document.write( "Chris' age: x+3
\n" ); document.write( "Andy's age: x+5+3 or x+8\r
\n" ); document.write( "\n" ); document.write( "Then, you are given that in 3 years, the sum of the ages is 35 so:\r
\n" ); document.write( "\n" ); document.write( "(x+3) + (x+8) = 35
\n" ); document.write( "x+x+3+8 = 35
\n" ); document.write( "2x+11=35
\n" ); document.write( "2x+11-11=35-11
\n" ); document.write( "2x=24
\n" ); document.write( "2x/2=24/2
\n" ); document.write( "x = 12\r
\n" ); document.write( "\n" ); document.write( "Substitute this solution back in to make sure it is correct.
\n" ); document.write( "Chris' age = 12
\n" ); document.write( "Andy's age = 17\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
