hope this helps!.
Y= 2x-4
4x+Y=2
4x+2x-4=2
6x-4=2
+4=+4
6x=6
6/6X = 6/6 X=1
Y=2X-4
2(1)-4
Y=-2
4c + 3p = 10.93....multiply by 7
7c + 2p = 13.31....multiply by -4
--------------------
28c + 21p = 76.51 (result of multiplying by 7)
-28c - 8p = - 53.24 (result of multiplying by -4)
------------------add
13p = 23.27
p = 23.27/13
p = 1.79 <== cost of 1 pencil pack
1.79/10 = 0.179 rounds to 0.18 <== unit price per pencil
