1st multiply the top equation by 3 and the bottom by 2 to be able to eliminate the y components

- anonymous

5x + 2y = -7 |x3| --> 15x+6y = -21
7x - 3y = 11 |x2| --> 14x-6y=22
you got x, then search for y

Do you understand?

- anonymous

after multiplying by 3 and 2 i add the 2 equations together to get x right

- anonymous

1/29?

- anonymous

yes thats correct for x now plug that back into one of the equations to solve for y

- anonymous

ok this is where i keep getting stuck i can not for the life of me figure out how to do that

- anonymous

what numbers do i multiply or whatever im suppose to do

- anonymous

5x+2y=-7
change x with 1/29

- anonymous

5(1/29) + 2y = -7
2y = -7 - (5/29)
So. y = [-7-(5/9)] / 2

- anonymous

so then is the answer 70/29

- anonymous

cant be im so confused

- anonymous

no, the answer is x = 1/29 and y = -3.59

- anonymous

thats where i keep getting stuck, how u got that for y, will u put it in laimens terms

- anonymous

5(1/29) + 2y = -7
2y = -7 - (5/29)
So. y = [-7-(5/9)] / 2 --> = -3.59

- anonymous

just follow what I did there and you should get it

- anonymous

5(1/29) + 2y = -7 --> 5/29 +2y=-7
2y = -7 - (5/29)
2y = (-203-5)/29
2y = -208/29
y = -208/29 * 1/2
y = -104/29

- anonymous

ok, but im still confused i am really really bad when it comes to this type of math
it helps me to make notes how did you get the -203? i need explanations for every answer except the obvious ones

- anonymous

make -7 in a fraction with denominator is 29, 29*-7=-203

- anonymous

ok and then u subtract -5 from that

- anonymous

okay I will walk you through it:
So we have x= 1/29 now you know how we got that
so plug 1/29 into 5x + 2y = -7
This becomes 5(1/29) + 2y = -7 -----> 5(1/29) = 5/29
So, subtract 5/29 from both sides:
2y = -7 - (5/29) -------Evaluate that
Then divide by 2:
Then y = [-7-(5/29)] / 2
and y = -3.59
So x = 1/29 and y = -3.59

- anonymous

the solution is (1/29,-104/29)

- anonymous

-104/29 is a fraction form from -3.59

- anonymous

yeah you can leave it in fraction form its more accurate, I just evaluated it

- anonymous

ok ty so much for you guys help and the trouble it took, thank you for being patient with me

- anonymous

hehe not a problem

- anonymous

no problem glad we could help!

- anonymous

tina, you understood the procedure, right?
