system of equations

OpenStudy (anonymous):

The system of equations -5x - 2y = 27 -3x + 3y = 12 is graphed below. Find the solution to the system.

OpenStudy (anonymous):

x = -4, y = -1 x = -1, y = -5 x = -5, y = -1 x = -5, y = 0

OpenStudy (anonymous):

x=-5, y=-1

hey, why are you facing problem in such questions? that are clear from graphs... do, you want me to tell you some concepts

OpenStudy (anonymous):

well im checking my work,

OpenStudy (anonymous):

how about that one? ^

OpenStudy (anonymous):

solve using elimination

hm okay, 2x+2y=18 8x-7y= -33

OpenStudy (anonymous):

multiply first by 4 8x+8y=72 8x-7y=-33 subtract 15y=105 y=105/15=7 find x by putting y 2x+14=18 x=2

OpenStudy (anonymous):

are you good in geometry?

OpenStudy (anonymous):

may be
