Keegan's age now = x
\n" ); document.write( "Lindsey's age now = x + 96
\n" ); document.write( "
\n" ); document.write( "\"7 years ago, Lindsey's age was 4 times Keegan's age\":
\n" ); document.write( "
\n" ); document.write( "(x + 96) - 7 = 4(x - 7)
\n" ); document.write( "
\n" ); document.write( "Solve for x:
\n" ); document.write( "
\n" ); document.write( "x + 96 - 7 = 4x - 28
\n" ); document.write( "
\n" ); document.write( "x + 89 = 4x - 28
\n" ); document.write( "
\n" ); document.write( "3x = 117
\n" ); document.write( "
\n" ); document.write( "x = 39
\n" ); document.write( "
\n" ); document.write( "Keegan's age now = x = 39
\n" ); document.write( "
\n" ); document.write( "Double-check:
\n" ); document.write( "
\n" ); document.write( "Keegan's age now = x = 39
\n" ); document.write( "Lindsey's age now = x + 96 = 135
\n" ); document.write( "
\n" ); document.write( "\"Keegan is 96 years younger than Lindsey\":
\n" ); document.write( "
\n" ); document.write( "135 - 39 = 96
\n" ); document.write( "
\n" ); document.write( "\"7 years ago, Lindsey's age was 4 times Keegan's age\":
\n" ); document.write( "
\n" ); document.write( "(135 - 7) = 4(39 - 7)
