you there?
Destinyyyy
  • Destinyyyy
Yes
anonymous
  • anonymous
ok, lets go through the steps
Destinyyyy
  • Destinyyyy
Guess its wrong then
anonymous
  • anonymous
ok we have 2 equtions
anonymous
  • anonymous
x + y = 35 121x + 83y = 3741
anonymous
  • anonymous
are those the equations you got?
Destinyyyy
  • Destinyyyy
Yes
anonymous
  • anonymous
great
anonymous
  • anonymous
isolate x in the first equation x=35-y
anonymous
  • anonymous
plug in 35-y for x in the second equation
Destinyyyy
  • Destinyyyy
x=8,072.6
anonymous
  • anonymous
121(35-y) + 83y = 3741
Destinyyyy
  • Destinyyyy
I miss calculated 121x-83x.. I wrote 30 down instead of 38
anonymous
  • anonymous
ok
anonymous
  • anonymous
tell me what you get
Destinyyyy
  • Destinyyyy
x=8072.6 and y= 8037 correct?
anonymous
  • anonymous
nope
Destinyyyy
  • Destinyyyy
-.-
anonymous
  • anonymous
Do you understand how i got to 121(35-y) + 83y = 3741
anonymous
  • anonymous
I explained it above
Destinyyyy
  • Destinyyyy
-83(x+y)=35 121x+83y=3741 -83x-83y=-2,905 --------------- 38x = -2,905 --- ----- 30 30 x=-96.83
anonymous
  • anonymous
why -83(x+y)=35?
anonymous
  • anonymous
it should just be x+y=35
Destinyyyy
  • Destinyyyy
Thats what my examples are from MyMathLab
Destinyyyy
  • Destinyyyy
It solves that way.. I have no clue what you were showing me
anonymous
  • anonymous
I have the answer, -83(x+y)=35 doesn't make any sense
Destinyyyy
  • Destinyyyy
-96.83+y=35 + + y=131.83
anonymous
  • anonymous
it says only 35 people were hired, how can there be 131.83 laborers?
anonymous
  • anonymous
Do you want me to show you how i got the answer?
Destinyyyy
  • Destinyyyy
Hold on.. Let me start over
anonymous
  • anonymous
These are the equations x + y = 35 121x + 83y = 3741
Destinyyyy
  • Destinyyyy
Yes
anonymous
  • anonymous
isolate x in the first equation x=35-y
anonymous
  • anonymous
plug in 35-y for x in the other equation
anonymous
  • anonymous
121(35-y) + 83y = 3741
anonymous
  • anonymous
solve for y
Destinyyyy
  • Destinyyyy
x=22 and y= 13 ... Do you want me to show you how i got it?
anonymous
  • anonymous
thats what i got, good job
anonymous
  • anonymous
to see if these are right, plug them back into the original equations
Destinyyyy
  • Destinyyyy
-83(x-y)=35 the -83 is meant to cancel out the 83y in the other equation
Destinyyyy
  • Destinyyyy
Im good
anonymous
  • anonymous
22+13 = 35
anonymous
  • anonymous
first equation works
anonymous
  • anonymous
121(22)+83(13)=3741
