4/7 the question is relative
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)

Answer:
w = -z(-w) + 3(-w)
Step-by-step explanation:
z = w + 3 | Given
-w + z = 3 | Subtract w from both sides.
-w = -z + 3 | Subtract z from both sides
w = -z(-w) + 3(-w) | Multiply -w on both sides.
