bogdanovich [222]
Cherry pie  is $ C.
Pumpkin pie is $ P.

C +   9P =60 -------> C=60 - 9P
11C+4P = 90  

11(60 - 9P) +4P=90
660 - 99P + 4P = 90
-95P = -570
P =570/95 = 6
P=6
C=60-9*P=60 - 9*6= 60-54=6
C=6

Answer: 1 cherry pie -$6, 1 pumpkin pie - $6.

Check:
11C+4P = 90  , 11*6 +4*6 =90, 66+24=90, 90=90 True

Solving for y:

6y - 2x = 20

6y = 2x + 20

y = \frac{2x + 20}{6}

y = \frac{2x}{6} + \frac{20}{6}

y = \frac{1x}{3} + \frac{10}{3}

<em>Hope it helps!</em>
