    plug in 35-y for x in the second equation

    -83(x+y)=35 121x+83y=3741 -83x-83y=-2,905 --------------- 38x = -2,905 --- ----- 30 30 x=-96.83

    it should just be x+y=35

    I have the answer, -83(x+y)=35 doesn't make any sense

    -96.83+y=35 + + y=131.83

    it says only 35 people were hired, how can there be 131.83 laborers?

    These are the equations x + y = 35 121x + 83y = 3741

    plug in 35-y for x in the other equation

    to see if these are right, plug them back into the original equations

    -83(x-y)=35 the -83 is meant to cancel out the 83y in the other equation
