1. 5x-y=4
2. -4/3+1/3y-2/3z
3. x=5+1/2y -3/2z
And/or the answer to the whole thing could be that the statement is incorrect.
Answer:
(-1, -5)
Step-by-step explanation:

1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)
Answer:
y= 4x+8
Step-by-step explanation:
you multiply 4 by X which equals 4X
the multiply the four by the two which equals eight
the last pair is statements are true.
