-3x + 5y = -5

A. (1,-1)
b. (0,0)
c. (0,-1)
D. (1,0)

Answer 1

you want to check the answers given, or just go ahead and solve?

Answer 2

just go ahead and solve its my daughters paper i just am checking the right answer

Answer 3

should be pretty clear that \((0,0)\) doesn't work, since that would give you \(0\) and not \(3\)

Answer 4

yea but which one is the corect answer

Answer 5

or solve \[-6x - 3y= 3\\ -3x + 5y = -5 \] by multiplying the second equation by \(-2\) to get the system \[-6x-3y=3\\6x-10y=10\]

Answer 6

add the two equations (in a column) and get
\[-13y=13\] which tells you \(y=-1\)

Answer 7

yea

Answer 8

put \(-1\) in for \(y\) in either equation, and you will find that \(x=0\)

Answer 9

okay thank you

Answer 10

for example
\[-6x - 3y= 3\\-6x-3\times -1=3\\-6x+3=3\\-6x=0\\x=0\]
