You can put this solution on YOUR website!
let j = Jane's present age
\n" ); document.write( "let b = Beth's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\" 3 times Jane's age in years is equal to 8 times Beth's age in years\"
\n" ); document.write( "3j = 8b
\n" ); document.write( ":
\n" ); document.write( "\" the difference between their ages is 15 years\"
\n" ); document.write( "j - b = 15
\n" ); document.write( "j = (b+15)
\n" ); document.write( ":
\n" ); document.write( "Replace j with (b+15) in the 1st equation
\n" ); document.write( "3(b + 15) = 8b
\n" ); document.write( "3b + 45 = 8b
\n" ); document.write( "45 = 8b - 3b
\n" ); document.write( "45 = 5b
\n" ); document.write( "b = $\"45%2F5\"$
\n" ); document.write( "b = 9
\n" ); document.write( ":
\n" ); document.write( "You can find j using the equation: j = (b+15)
