Question

For which system of equations is (–2, 2) the solution?
A.
3x – 5y = –16
–2x + 3y = 10
B.
–4x + 2y = 6
2x – 3y = 10
C.
4x + 3y = 2
5x + 4y = –2
D.
6x + 5y = –2
–8x + 5y = –6

Answer 1

substitute x=-2 into the equations

Answer 2

if u get y=2,that will be ur correct equation

Answer 3

Let's check one by one

Answer 4

Option A...

Answer 5

\[3x-5y=-16\]\[-2x+3y=10\]

Answer 6

substitute x=-2 into the equation

Answer 7

\[3(-2)-5y=-16\]\[-2(-2)+3y=10\]

Answer 8

if u get y=2,that equation is correct

Answer 9

\[-6-5y=-16\]\[4+3y=10\]

Answer 10

i know it not B bc it just doesn't have y=2

Answer 11

\[-5y=-16+6\]\[3y=10-4\]\[-5y=-10\]\[3y=6\]\[y=2,y=2\]

Answer 12

its C!

Answer 13

nope

Answer 14

Option B...

Answer 15

\[-4x+2y=6\]\[2x-3y=10\]\[-4(-2)+2y=6\]\[2(-2)-3y=10\]

Answer 16

\[8+2y=6\]\[-4-3y=10\]

Answer 17

its A?

Answer 18

\[2y=6-8\]\[-3y=10+4\]

Answer 19

yep :)
