 price of a sheep is twice that of a goat

Let x represent the price of a goat and 2x the price of a sheep

Question states***



Solve for x, determine 2x and then find the total price of 3 goats and 2sheep

 goat price = x

sheep price =y



(12x+12y)/24  is the average price



(12x+12y)/24=600



12x+12y=24*600



/12

x+y=1200.......................(1)



y= 2x...........................(2)



substitute y=2x in )1)



x+2x=1200

3x=1200

x=400



y=2x

so y=800
