Y=4-7x
because it equals = -7
and
y= -5/4x + 2
because it equals = -5/4
The answer of this equation is 8cm I did the math
<em>x = markers</em>
<em>y = colored pencils</em>
12x = y
x= 72
y = 6
Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 <em>(12x = 6) </em>which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.
I think the answer should be 4.7 but rounded up would be 5
