You can put this solution on YOUR website!
let L =Luis' age
\n" ); document.write( "let b = Bill's age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( " Luis is 6 years older than Bill.
\n" ); document.write( "L = b + 6
\n" ); document.write( " In 12 years, the sum of their ages is 60.
\n" ); document.write( "(L+12) + (b+12) = 60
\n" ); document.write( "L + b + 24 = 60
\n" ); document.write( "L + b = 60 - 24
\n" ); document.write( "L + b = 36
\n" ); document.write( "from the first equation, replace with (b+6)
\n" ); document.write( "(b+6) + b = 36
\n" ); document.write( "2b = 36 - 6
\n" ); document.write( "2b = 30
\n" ); document.write( "b = 15 yrs is Bills age
\n" ); document.write( ":
\n" ); document.write( "I'll let you find Luis' age
\n" ); document.write( ":
\n" ); document.write( "Check your solution in both statement\r
