Solve the following system of equations: x - 2y = 14 x + 3y = 9

OpenStudy (anonymous):

(1, 12) (-1, -12) (12, -1) (12, 1)

OpenStudy (anonymous):

please help

OpenStudy (anonymous):

if you substitute the answer choices into the problem you will find the answer is C. \[(12)-2(-1)=14\] \[(12)+3(-1)=9\]

OpenStudy (anonymous):

the first number is your x value and your second number is the y value. (x,y)

OpenStudy (anonymous):

theres no answer like that

OpenStudy (anonymous):

the answers are(1, 12) (-1, -12) (12, -1) (12, 1)

OpenStudy (anonymous):

(12,-1)

OpenStudy (anonymous):

so the answer would be the third one, yes? I'm assuming those are your choices for the answer correct?

OpenStudy (anonymous):

the answer would be (12,-1), because like I showed you when you plug it into the equation the answers come out correct

OpenStudy (anonymous):

Ab60093 gave you the answer, it's (12,-1)
