Answer:
-38/4, -2 38/4, -4 38/4, -6 38/4
Step-by-step explanation:
x+(x+2)+(x+4)+(x+6) = -26
4x+12=-26
4x= -38
x=-38/4
I think it’s 16 because 1/3=3/9 of hardcover books

2/9 is DVDS
72/9=8
8x2=16

Answer:
x=1.25 and y=-5.5
Step-by-step explanation:
2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25
