Answer: -26
Step-by-step explanation: hope this helps :)
There are 12 months in one year. To find how many pounds of vegetables each person ate, divide 208 by 12 to get 17.33333 or 17 1/3. The average person ate 17.33333 pounds of vegetables per month last year. To find how many pounds of fruit the average person ate each month, divide 125 5/8 by 12 to get 10.46875 or 10 15/32. If the fruits and vegetables are combined, add 208 and 125 5/8 together and divide by 12 to get 27 77/96 or 27.80208.
The average person ate 17.33333 pounds of vegetables per month.
The average person ate 10.46875 pounds of fruits per month.
The average person ate 27.80208 pounds of combined fruits and vegetables per month.

Answer:
Step-by-step explanation:
2x + z = 9.....z = -2x + 9
so we r gonna sub in -2x + 9 for z in our other 2 equations
3x + 2y + z = 9 -3x - y + 3z = -7
3x + 2y + (-2x + 9) = 9 -3x - y + 3(-2x + 9) = -7
3x + 2y - 2x + 9 = 9 -3x - y - 6x + 27 = -7
x + 2y = 9 - 9 - 9x - y = -7 - 27
x + 2y = 0 -9x - y = - 34
now we take our results and eliminate a variable
x + 2y = 0
-9x - y = -34.....multiply by 2
-------------------
x + 2y = 0
-18x - 2y = - 68 (result of multiplying by 2)
------------------add
-17x = -68
x = -68/-17
x = 4
now we sub 4 in for x in either of our resulting equations
x + 2y = 0
4 + 2y = 0
2y = 0 - 4
2y = -4
y = -4/2
y = -2
now that we know x and y, sub these values in to any of the original equations to find z
z = -2x + 9
z = -2(4) + 9
z = -8 + 9
z = 1
check it...
3x + 2y + z = 9
3(4) + 2(-2) + 1 = 9
12 - 4 + 1 = 9
8 + 1 = 9
9 = 9 (correct)...and it checks out
solution is : (4,-2,1) <====
