Let x=Fred's age
\n" ); document.write( "Then Jim's age = 3x-4
\n" ); document.write( "If we double Fred's age, we get 2x
\n" ); document.write( "Now if we add this to Jim's age we get:
\n" ); document.write( "2x+(3x-4)and we are told that this equals 56, so our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "2x+3x-4=56 add 4 to each side\r
\n" ); document.write( "\n" ); document.write( "2x+3x-4+4=56+4 collect like terms
\n" ); document.write( "5x=60 divide each term by 5\r
\n" ); document.write( "\n" ); document.write( "x=12-----------------------------------------------Fred's age\r
\n" ); document.write( "\n" ); document.write( "3x-4=3*12-4=36-4=32 ------------------------------Jim's age\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "Jim's age is 4 years less than 3 times Fred's age
\n" ); document.write( "3*12-4=32
\n" ); document.write( "32=32
\n" ); document.write( "if Fred's age is doubled and added to Jim's age the result is 56.
\n" ); document.write( "2*12+32=56
\n" ); document.write( "56=56\r
