Two gallons of crude oil were poured into two containers of different sizes. Use one variable to express the amount of oil poured into each container. Let g represent the number of gallons of oil in the first container. How many gallons of oil are in the second container?
Step 1:  We are given that there is a total of gallons of crude oil.
This means that the sum of the two containers is equal to gallons.
Step 2:  The first container holds g gallons.
The sum of the first container (g gallons) and the second container is gallons.
Step 3:  Translate this statement into into a variable expression.
g gallons + number of gallons in second container = gallons
Step 4:  Subtract g from both sides
number of gallons in second container = gallons - g gallons
The number of gallons in the second container is expressed as
.
