A is eleven times as old as B.
\n" ); document.write( "A = 11B
\n" ); document.write( "-------------
\n" ); document.write( "in a certain number of years, A will be five times as old as B
\n" ); document.write( "A+x = 5(B+x)
\n" ); document.write( "-------------
\n" ); document.write( "and in five years after that she will be three times as old as B.
\n" ); document.write( "A+x+5 = 3(B+x+5)
\n" ); document.write( "-----------------
\n" ); document.write( "how old are they now?
\n" ); document.write( "-------
\n" ); document.write( "Rearrange the three equations with variables A, B, and x
\n" ); document.write( "A - 11B + 0x = 0
\n" ); document.write( "A - 5B -4x = 0
\n" ); document.write( "A -3B - 2x = 10
\n" ); document.write( "---------------
\n" ); document.write( "Solve the systems of three equations by any method to get:
\n" ); document.write( "A = 22
\n" ); document.write( "B = 2
\n" ); document.write( "x = 3
\n" ); document.write( "-----------
\n" ); document.write( "A is 22 yrs. old
\n" ); document.write( "B is 2 yrs. old
\n" ); document.write( "======================
