\n" ); document.write( "When the circus came to town last year, they hired general labors at $70 per day and mechanics at $90 per day. They paid $1950 foe this temporary help for one day. This year they hired exactly the same number of people of each type, but they paid $80 for general labors and $100 for mechanics for one day. This year they paid $2200 for temporary help. How many general laborers did they hire? How many mechanics did they hire?

You can put this solution on YOUR website!
x= number of general laborers
\n" ); document.write( "y= number of no of mechanics
\n" ); document.write( "
\n" ); document.write( "70.00 x + 90.00 z = 1950.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "80.00 x + 100.00 z = 2200.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -10.00
\n" ); document.write( "Multiply (2) by 9.00
\n" ); document.write( "-700.00 x -900.00 z = -19500.00
\n" ); document.write( "720.00 x + 900.00 z = 19800.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "20.00 x = 300.00
\n" ); document.write( "/ 20.00
\n" ); document.write( "x = 15.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "70.00 x + 90.00 z = 1950.00
\n" ); document.write( "1050.00 + 90.00 z = 1950.00
\n" ); document.write( " 90.00 z = 1950.00 -1050.00
\n" ); document.write( " 90.00 z = 900.00
\n" ); document.write( " z = 10
\n" ); document.write( "x= 15 number of general laborers
\n" ); document.write( "y= 10 number of no of mechanics
