3x+y= -7y= x in need help

x=0   y=0

Step-by-step explanation:

3x + y = -7y = x

cancel out all y's

3x+ y(0) = -7(0) = x

3x  =x

-x    -x

2x = 0

divide both sides by 2

x=0

3x + y = -7y =x

cancel out all x's

3(0) +y = -7y = x(0)

y=-7y

-y  -y

0 = -7y

divide both sides by -7

y=0

hope this helps!
