Answer:
The expression of amount of gas is 
Step-by-step explanation:
Given:
25 gallons of gas were pumped into two different size tanks.
Now, to express the amount of gas pumped into the smaller tank in terms of the amount
pumped into the larger tank.
Let the amount of gas pumped into smaller tank be 
And according to question, the amount of gas pumped into larger tank is
.
Total amount of gas pumped into both size tanks = 25 gallons.
So, to express the amount of gas pumped into the smaller tank in terms of the amount
pumped into the larger tank:

<em>Subtracting both sides by </em>
<em> we get:</em>

Therefore, the expression of amount of gas is
