you there?

- Destinyyyy

Yes

- anonymous

ok, lets go through the steps

- Destinyyyy

Guess its wrong then

- anonymous

ok we have 2 equtions

- anonymous

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

- anonymous

are those the equations you got?

- Destinyyyy

Yes

- anonymous

great

- anonymous

isolate x in the first equation
x=35-y

- anonymous

plug in 35-y for x in the second equation

- Destinyyyy

x=8,072.6

- anonymous

121(35-y) + 83y = 3741

- Destinyyyy

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

- anonymous

ok

- anonymous

tell me what you get

- Destinyyyy

x=8072.6 and y= 8037 correct?

- anonymous

nope

- Destinyyyy

-.-

- anonymous

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

- anonymous

I explained it above

- Destinyyyy

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

- anonymous

why -83(x+y)=35?

- anonymous

it should just be x+y=35

- Destinyyyy

Thats what my examples are from MyMathLab

- Destinyyyy

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

- anonymous

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

- Destinyyyy

-96.83+y=35
+ +
y=131.83

- anonymous

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

- anonymous

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

- Destinyyyy

Hold on.. Let me start over

- anonymous

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

- Destinyyyy

Yes

- anonymous

isolate x in the first equation
x=35-y

- anonymous

plug in 35-y for x in the other equation

- anonymous

121(35-y) + 83y = 3741

- anonymous

solve for y

- Destinyyyy

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

- anonymous

thats what i got, good job

- anonymous

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

- Destinyyyy

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

- Destinyyyy

Im good

- anonymous

22+13 = 35

- anonymous

first equation works

- anonymous

121(22)+83(13)=3741

- Destinyyyy

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

- anonymous

those the right answers

- anonymous

k, don't forget to medal

- Destinyyyy

Thanks for your help.

- anonymous

no problem
