600 for oil, 100 for wood

Step-by-step explanation:

I did this in my head but if you want the equation it is 6x+x=700, combine like terms to get 7x=700 then divide by 7 to get x=100. think of it as 6 times the cost for wood plus the cost of wood gives the total of 700 as that's the equation in word form. to get the number for oil take 6x or 100 (6) to get 600.
