Last year's salaries are in 3+4=7 parts.
\n" ); document.write( "If x is a factor for those salaries, then \"x%283%2F7%29\" for A and \"x%284%2F7%29\" for B.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This year, \"%285%2F4%29%2Ax%283%2F7%29\" for A and \"%283%2F2%29%2Ax%284%2F7%29+\"for B.
\n" ); document.write( "Remember, x was assigned as a variable, a factor, and NOT as an operation symbol.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Total salaries of A and B combined for \"this year\" is Tk. 4160.

\n" ); document.write( "Solve for x, and then you can evaluate any or all of this year and last year salaries
