My answer is--- x= 10225.4 and y= -10190.4 are my answers right?

Answer 2

x= equipment operators and y= laborers

Answer 3

@whpalmer4

Answer 4

you there?

Answer 5

Yes

Answer 6

ok, lets go through the steps

Answer 7

Guess its wrong then

Answer 8

ok we have 2 equtions

Answer 9

x + y = 35
121x + 83y = 3741

Answer 10

are those the equations you got?

Answer 11

Yes

Answer 12

great

Answer 13

isolate x in the first equation
x=35-y

Answer 14

plug in 35-y for x in the second equation

Answer 15

x=8,072.6

Answer 16

121(35-y) + 83y = 3741

Answer 17

I miss calculated 121x-83x.. I wrote 30 down instead of 38

Answer 18

ok

Answer 19

tell me what you get

Answer 20

x=8072.6 and y= 8037 correct?

Answer 21

nope

Answer 22

-.-

Answer 23

Do you understand how i got to
121(35-y) + 83y = 3741

Answer 24

I explained it above

Answer 25

-83(x+y)=35
121x+83y=3741

-83x-83y=-2,905
---------------
38x = -2,905
--- -----
30 30
x=-96.83

Answer 26

why -83(x+y)=35?

Answer 27

it should just be x+y=35

Answer 28

Thats what my examples are from MyMathLab

Answer 29

It solves that way.. I have no clue what you were showing me

Answer 30

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

Answer 31

-96.83+y=35
+ +
y=131.83

Answer 32

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

Answer 33

Do you want me to show you how i got the answer?

Answer 34

Hold on.. Let me start over

Answer 35

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

Answer 36

Yes

Answer 37

isolate x in the first equation
x=35-y

Answer 38

plug in 35-y for x in the other equation

Answer 39

121(35-y) + 83y = 3741

Answer 40

solve for y

Answer 41

x=22 and y= 13 ... Do you want me to show you how i got it?

Answer 42

thats what i got, good job

Answer 43

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

Answer 44

-83(x-y)=35

the -83 is meant to cancel out the 83y in the other equation

Answer 45

Im good

Answer 46

22+13 = 35

Answer 47

first equation works

Answer 48

121(22)+83(13)=3741

Answer 49

I already got an A on my test, Thanks for you help. It was a calculation error on my end.

Answer 50

those the right answers

Answer 51

k, don't forget to medal

Answer 52

Thanks for your help.

Answer 53

no problem
