x = -3 -y
2(-3 -y) =0
-6 -2y = 0
-2y = 6
y = -3

Answer:
189
Step-by-step explanation:
If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.

Answer:$14701
Step-by-step explanation:
1) at the end of the first year the account will be 1*(12 000)+0,07*(12 000)=1,07*12 000,
2) at the end of the second year 1*(1.07*12 000) + 0.07*(1.07*12 000) = 1.1449*12 000,
3) at the end of the third year 1*(1,1449*12 000) + 0.07*(1,1449*12 000) = 1.225*12 000 = 14,700.516 = 14701
