\n" ); document.write( "Darius is 87 years younger than jack. 11 years ago, jacks age was 4 times Darius’s age. How old is Darius now? X= current age of Darius. the equation should contain 87,11, & 4.
\n" ); document.write( "I tried solving it this way (x-11)=4(x-87-11) but it’s not adding up right
\n" ); document.write( "

With X being Darius' age, Jack is X + 87
\n" );
document.write( "We then get: X + 87 - 11 = 4(X - 11) <====== CONTAINS 87, 11, and 4
\n" );
document.write( "X + 76 = 4X - 44
\n" );
document.write( "X - 4X = - 44 - 76
\n" );
document.write( "- 3X = - 120
\n" );
document.write( "X, or  \n" );
document.write( "

\n" );
