-1/4 is between -2/6 and -1/6
Answer:

Step-by-step explanation:

from equation 1 we get,

now,

we get,

now,

we get,

hence, the value of x = 3 and y = (-1)
-(-2x-6y=-16)
2x+6y=16
4x-6y=-58
Y's cancel out, then add the rest
6x=-42
divide both sides by six
x=-7
plug x into any previous equation
2(-7)+6y=16
-14+6y=16
6y=30
y=5
