Gressel the Goblin is making an inventory of Darklord Ganondorf’s treasure horde following a raid by some violent fellow named link. The horde now contains only 2150 gems (as in $). Gressel notices that there were twice as many green-gems (worth 1) as blue-gems (worth 5) and 13 fewer blue gems than red-gems (worth 20). How many red, blue and green gems are there remaining in the horde?

Answer:

70   blue gems

 

140  green gems

 

83  red gems

Step-by-step explanation:

x + 1*2x  + 20 ( x+ 13)  =  2150   simplify

 

27x + 260 =  2150

 

27x  = 2150 - 260

  the   number of blue  gems  =  x

the number of   green gems  = 2x

the  number of red  gems = x + 13

 

which means  

5x  + 1*2x  + 20 ( x+ 13)  =  2150   simplify

 

27x + 260 =  2150

 

27x = 2150 - 260

 

27x  = 1890
