Let x = Kelly's current age
\n" ); document.write( "Matt's current age is 5x+1\r
\n" ); document.write( "\n" ); document.write( "Kelly's age in 3 years = x+3
\n" ); document.write( "Matt's age in 3 years = 5x+1+3\r
\n" ); document.write( "\n" ); document.write( "Matt's age in 3 years = 3 times Kelly's age in 3 years
\n" ); document.write( "5x+1+3 = 3(x+3)
\n" ); document.write( "5x+4=3x+9
\n" ); document.write( "subtract 4 from both sides
\n" ); document.write( "5x=3x+5
\n" ); document.write( "subtract 3x from both sides
\n" ); document.write( "2x=5
\n" ); document.write( "divide both sides by 2 to get x by itself
\n" ); document.write( "x=2.5\r
\n" ); document.write( "\n" ); document.write( "answer: Kelly is 2.5 years old
\n" ); document.write( "Matt is 5(2.5)+1 = 13.5 years old
\n" ); document.write( "
