OpenStudy (ronlover101):

Which ordered pair is the solution to the system of equations? A. (1, 7) B. (4, 9) C. (7, 19) D. (8, 21)

OpenStudy (anonymous):

Multiply the first question by 3 and to the second equation. Solve for x. Then find the answer that has that same value as x.

OpenStudy (anonymous):

* and add to the second equation

OpenStudy (ronlover101):

sorry please stop]

OpenStudy (anonymous):

oh, ok.

OpenStudy (ronlover101):

after the question I asked I forgot to put 2x-y=-5 x+3y=23

OpenStudy (anonymous):

Alright. Then, your answer would be A.

OpenStudy (ronlover101):

thank you!!!

OpenStudy (ronlover101):

may I ask another question?

OpenStudy (anonymous):

Sure

OpenStudy (ronlover101):

Which ordered pair is the solution to the system of equations? -3x+4y=-20 x+4y=-4 A. (8, 1) B. (−12, 2) C. (−4, −8) D. (4, −2)

OpenStudy (anonymous):

The answer would be (-7,-2) <-- plug 4y > -5 + x 4(-2) > -5 + -7 -8 > -12

OpenStudy (ronlover101):

but that is not one of the answers

OpenStudy (anonymous):

Sorry, it would be c, posted on the wrong question. Sorry about that.

OpenStudy (ronlover101):
