0.3x-0.2y=4
0.5x+0.3y=71/23
so, first you have to get rid of the y from both equations

- anonymous

right! i'm clueless, the fraction throws me off!

It is simple:
multiply both equations, so that the y members of both of them are eliminated when added
so in your case, we can multiply the first equation by 3, to get 0.9x-0.6y=12
and now we need to multiply the second equation in such a way that when coresponding members of both of them are added, y is eliminated (equals zero)
so, we have to multiply it by 2 to get 1x+0.6y=142/23

- anonymous

now, we have to add all coresponding members to eliminate y, so
0.9x-0.6y=12
+ 1x+0.6y=142/23

1.9x+0=418/23
=1.9x=418/23

- anonymous

ok, i follow you so far ....

- anonymous

so, now lets solve for x
1.9x=418/23
23*1.9x=418
43.7x=418
x=418/43.7
x=9.56521

- anonymous

i have to solve it as a fraction, so i'm plugging in 418/43.7 to solve for y ....

- anonymous

now to get y we just take any equation, and substitute x into it, and solve for y
0.3x-0.2y=4
0.3*9.56521-0.2y=4
2.869565217-0.2y=4
-0.2y=4-2.869565217
-0.2y=1.130434
y=1.130434/-0.2
y=-5.65

if I helped in anyway, I would apreciate if you would fan me (reload this page, and click a blue Become a fan button near my name)

- anonymous

x~~9.56522, y~~-5.65217

- anonymous

yes, thats correct

- anonymous

what is y as a fraction?

- anonymous

that is y as a decimal

- anonymous

my answer has to be in the form of a fraction

to get it as a fraction, just do same steps as I showed you, just keep pluging in fractions all the way from the beginning until now, and you can get a fraction

- anonymous

x=220/23

- anonymous

ok, thx! and i became a fan while you were working on my problem, thx!

- anonymous

y=-130/23

- anonymous

Got the fraction?

- anonymous

x=220/23
y=-130/23

- anonymous

great, thx!

- anonymous

You are welcome, and look at the plot that will help you understand
