Can someone help me with math? i will tell question inside

OpenStudy (anonymous):

ask

OpenStudy (anonymous):

sorry, comp is making it some weird symbol

OpenStudy (anonymous):

its 3x + 2y = -17 and 5x - 4y = -19

OpenStudy (anonymous):

answers are There is no solution. The solution is (–4, 2). The solution is (–3, 1). There are an infinite number of solutions.

OpenStudy (jhannybean):

Use the method of elimination

OpenStudy (anonymous):

my computer keeps buggin and making the symbols and i am trying

OpenStudy (anonymous):

whats the answers

OpenStudy (anonymous):

no solution infinite solutions (-4, 2) and (-3,1)

OpenStudy (jhannybean):

3x + 2y = -17 5x - 4y = -19 _________________ -5(3x +2y = - 17) 3(5x -4y =-19) _______________________ Expand those two and tell me what two equations you end up with.

OpenStudy (anonymous):

i got nothing for equation, but i did find a possible answer

OpenStudy (anonymous):

the possible answer i got is (-3,1)

OpenStudy (jhannybean):

got nothing for the equation? Expand: -5(3x +2y = - 17)

OpenStudy (anonymous):

ok,

OpenStudy (jhannybean):

Multiply -5 with each term within the parenthesis.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

i got nothing again, sorry for wasting time guys, i will just close this and give you a medal for all your help&troubles

OpenStudy (jhannybean):

You do not seem as if you are even attempting this problem.

OpenStudy (jhannybean):

It is impossible to get "nothing" from expanding the function.
