whatcha need help with?

- anonymous

how do i solve this system:
5x+2y =7
-x/2 + y/6 = 3/2
i have been trying to solve this but can't get it right, could you show me the steps!

- amistre64

I did that one on your other post, do you see it?

solve for y in the top:
y = -5x/2 +7/2
plug it into the bottom equation:
-x/2 + (-5x/2 +7/2)/6 = 3/2
Solve for x:
-x/2 -5x/12 +7/12 = 3/2
-6x/12 -5x/12 +7/12 = 18/12
-6x -5x +7 =18
-11x = 11
x=-1
Now that we have a solid number for x; plug it into the equation we found for y:
y = -5(-1)/2 +7/2
y= 5/2 + 7/2
y= 12/2 = 6
Double check for accuracy :)

ok thanks i really appreciate it, i have one other...
completing the square t^2 -9t_______
it says to first complete trinomial ____________________________
the then (_________________________)^2 bionomial squared...

- anonymous

for the first question... i was taught to plug 0 in.... how did you get 7/2 ....

- amistre64

Yes, to complete the square we need to find a term whose product adds up to (-9); which is just (-9/2)^2.

- amistre64

To solve for y:
subtract (5x) from both sides: 2y = -5x + 7
now divide everything by (2): (2/2)y = (-5/2)x + (7/2)
y = (-5/2)x + (7/2)

- anonymous

ok got that... and then this step confuses me
Solve for x:
-x/2 -5x/12 +7/12 = 3/2
-6x/12 -5x/12 +7/12 = 18/12

- amistre64

(t-(9/2))^2 = (t-(9/2)) (t-(9/2)) = t^2 -9 + 81/4

- anonymous

Solve for x:
-x/2 -5x/12 +7/12 = 3/2
-6x/12 -5x/12 +7/12 = 18/12

- anonymous

got me lost...

- anonymous

it started out different...

- anonymous

with the 6 on the bottoms and turned to tweleve why did you multiply

- amistre64

To solve for x: we need to get all the fractions having the same denominators.
The common denominator is 12:
-x/2 needs to be multiplied by 6/6 to get a 12 on the bottom: -6x/12
-5x/12 already gots a 12
+7/12 already gots a 12
3/2 needs to be multiplied by 6/6 to get 12 on bottom: 18/12
Now because everything has a 12 on the bottom, we can toss the 12 out to clean up the equation:
-6x -5x +7 = 18

- anonymous

but what happens to the 6 on the bottom of the 2nd fraction...

- amistre64

i see it:
we solved for y to get:
y = -5x/2 +7/2
The second equation has the term: y/6, so plug in what you found out about "y" to get:
(-5x/2 +7/2)/6 when we divide the 6 thru we get:
(-5x/2)/6 and (7/2)/6
the 6 actually multiplies to the bottom number, the 2. so that the denominators become 12.
Does that make sense? I can try explaining it another way if you like

- anonymous

i am writting it down sorry its taking me so long.. i really appreciate your help :)

- anonymous

ok i understand that now, so then once i have those answers (-x/2) (-5x/2)/6 (7/2)/6 = 3/2
what am i doing to get twelve?
becaues isn't (7/2)/6 technically .58

- amistre64

let me try it this way, cause fractions are terrible in this format.
top: (-5x)(1) +(7)(1) = -5x +7
bottom: (2) (6) (2)(6) = 12 12
How does that look? :)

- anonymous

more confusing i have wrritting out fine... with the fractions over 6 but don't get what i am doing
if i have 7/2 over 6 that equals .58

- amistre64

To divide fractions; flip the bottom one over and multiply across.
(7/2)/(6/1) is the same as (7/2)(1/6) = (7/12)

- amistre64

gotta run; have fun :)

thx
