Two tanks are filled to capacity with automobile fuel. The first tank holds 600 gallons more than the second tank. If 100 gallons were to be pumped from each tank, the first tank would then contain 3 times as much fuel as the second tank. What is the total number of gallons of fuel in the two full tanks?

best des
1st tank holds = a gallons
2nd tank holds = a + 600 gallons
100 gallons pumped out
so
a + 600 - 100 = (a - 100)*3
a = 400
1st tank holds = 400 gallons
2nd tank holds = 1000 gallons
1st tank + 2nd tank = 1400 gallons (ans)
