OpenStudy (aaronandyson):

Do you know method of elimination?

OpenStudy (kingogcobraxx):

yea..

OpenStudy (aaronandyson):

Use it to solve this equation.

OpenStudy (kingogcobraxx):

i have no idea how to do this

OpenStudy (aaronandyson):

5x + y = 2 4x + y = 4 subtract them. The signs change while subtracting.

OpenStudy (kingogcobraxx):

that didnt help whatsoever just alot of letters and numbers

OpenStudy (aaronandyson):

5x + y = 2 4x + y = 4 5x + y = 2 y = 2 - 5x putting this value of y in 4x + y = 4 4x + y = 4 4x + 2 - 5x = 4 -x+ 2 = 4 -x = 4-2 -x = 2 x = -2

OpenStudy (aaronandyson):

now use this value of x to find y

OpenStudy (kingogcobraxx):

12?

OpenStudy (aaronandyson):

correct!

OpenStudy (kingogcobraxx):

4 more?

OpenStudy (kingogcobraxx):

OpenStudy (welshfella):

HInt: multiply the first equation by 5 what do you get?

OpenStudy (kingogcobraxx):

no idea

OpenStudy (kingogcobraxx):

y cant multiply

OpenStudy (welshfella):

just multiply every term by 4 2x*5 + 5y*5 = -11*5

OpenStudy (yanasidlinskiy):

Or you could: Make them equal to Y FIRST: y=-2/5x-11/5 y=-10/25x-55/25 Simplify y=-2/5x-11/5 y=-2/5x--11/5 The lines are same so they will be touching the whole time so Infintely many

OpenStudy (welshfella):

5*2x = 10x - now try the other 2..

OpenStudy (kingogcobraxx):

fan and medal if you tell me the answer lol

OpenStudy (kingogcobraxx):

250 lol

OpenStudy (welshfella):

we are not supposed to give you answers but guide you to the result.

OpenStudy (kingogcobraxx):

exactly ... i suck at this

OpenStudy (yanasidlinskiy):

We learn here. Not just give out answers. I practically told you the answer already... Another way is you could simplify the 2nd equation by dividing by 5 you get 2x + 5y = -11 which is the 1st equation. So any point on this equation is a solution. Infinitely Many

OpenStudy (kingogcobraxx):

i just read that lol

OpenStudy (kingogcobraxx):

OpenStudy (yanasidlinskiy):

yup. How hard is it?

OpenStudy (yanasidlinskiy):

Solve for one of the equations. Next, plug it into either X or Y(whichever you solve for) Then you'll get it:)

OpenStudy (kingogcobraxx):

very hard

OpenStudy (kingogcobraxx):

i haave to get this done by midnight cmon man

OpenStudy (yanasidlinskiy):

Will you do my trig? Cmon man,(I ain't a guy) and we're here to learn. Not to just get answers.

OpenStudy (kingogcobraxx):

i call everyone man,bro..etc but whatever ill just click random answers

OpenStudy (yanasidlinskiy):

Oh wow ok:) Hopefully you pass:) Good Luck

OpenStudy (kingogcobraxx):

uh huh

OpenStudy (kingogcobraxx):

un fan lmao not even

OpenStudy (yanasidlinskiy):

Solve for the first equation. What do you get?

OpenStudy (kingogcobraxx):

nothing

OpenStudy (kingogcobraxx):

@YanaSidlinskiy

OpenStudy (yanasidlinskiy):

Oh dang. Try again

OpenStudy (kingogcobraxx):

same

OpenStudy (yanasidlinskiy):

Keep trying until you get something

OpenStudy (kingogcobraxx):

im getting off

OpenStudy (yanasidlinskiy):

Oh okay

OpenStudy (kingogcobraxx):

im just clicking random answers lmao 3 questions and you cant just tell me the answer

OpenStudy (kingogcobraxx):

getting off in

OpenStudy (kingogcobraxx):

5

OpenStudy (kingogcobraxx):

4

OpenStudy (kingogcobraxx):

3

OpenStudy (kingogcobraxx):

2

OpenStudy (kingogcobraxx):
