Best ResponseYou've already chosen the best response.0ok multiply x+y=55 times 12 12(x+y=55) 12x 12y = 660 and add to the next equation 13.50x + 12y = 705 ____________________________ 1.50x = 45 divide both sides by 1.50 x= 30 this is sheila's hours worked what is Glen's

Best ResponseYou've already chosen the best response.0all right next if you take the number of hours a person worked and multiply it by the amount they get paid per hour that is their total amount paid. but here we have two people so we add their amounts together remember sheila is x and glen is y so we have to multiply their no hours worked by what there hourly rate is sheila 13.50 * x glen 12 * y this will equal the total amount 705 dollars here is the second equation 13.50x + 12 y = 705 dollars
