3x+2y+z=352000 x6 18x+12y+6z=2112000
5x+3y+6z=637000 x1 5x+3y+6z=637000 -
13x+9y = 1475000
5x+3y+6z=637000 x1 5x+3y+6z=637000
4x+5y+3z=616000 x2 8x+10y+6z=1232000 -
-3x-7y = - 595000
13x+9y=1475000 x7 91x+63y= 10325000
-3x-7y=-595000 x9 -27x-63y = -5355000 +
64x = 4970000
x = 4970000/64
x = 77656,25
3x+7y=595000
3(77656,25) + 7y = 595000
232968.75 +7y = 595000
y = (595000 - 232968,75) / 7
= 362031,25 / 7
= 51718.75
3(77656.25) + 2(51718.75)+z=352000
232968.75 + 103437.5 + z = 352000
336406.25 + z = 352000
z = 15593.75
