are you sure you typed out those equations correctly? they look somewhat odd to me
Vocaloid
  • Vocaloid
ok, much better. we can start by multiplying the second equation by 6

-3x+2y=48
Vocaloid
  • Vocaloid
good, now we have: 3x + (1/4)y = (-3/4) -3x + 2y = 48 now add the two equations together

x+2.25y=47.25

don't think I'm supposed to have decimals

almost 3x - 3x = ?

  • ShadowLegendX
I know this one :)
anonymous

x
Vocaloid
  • Vocaloid
nope, not quite hint: 3 - 3 = 0 3x - 3x = ?
anonymous
  • anonymous
0x
ShadowLegendX
  • ShadowLegendX
There is no such thing as 0x That would be just 0...
Vocaloid
  • Vocaloid
good, and 0x = 0 because 0 times anything is 0 so now we have: 2.25y = 47.25 y = ?

21
ShadowLegendX
  • ShadowLegendX
2.25y is saying 2.25 times y. Negate that by dividing. Divide both sides by 2.25
anonymous
  • anonymous
i did that
anonymous
  • anonymous
y= 21
anonymous
  • anonymous
what about solving for X
Vocaloid
  • Vocaloid
ok, now we know that y = 21 we can solve for x by plugging in y = 21 back into one of the other equations
anonymous
  • anonymous
for both equations
Vocaloid
  • Vocaloid
-(1/2)x + (1/3)y = 8 -(1/2)x + (1/3)21 = 8 -(1/2)x + 7 = 8 x = ?
Vocaloid
  • Vocaloid
we only need to plug in y = 21 into one of the equations, since both will give us the same x value

.5
anonymous
  • anonymous
1/2
Vocaloid
  • Vocaloid
nope, not quite (-1/2)x + 7 = 8 subtract 7 from each side to get (-1/2)x = 1 x = ?
anonymous
  • anonymous
-.5
Vocaloid
  • Vocaloid
nope, check your math again
Vocaloid
  • Vocaloid
1/(-1/2) = ?
anonymous
  • anonymous
-2
Vocaloid
  • Vocaloid
good, so x = -2 and y = 21

thanks!
