Answer:
The required expression is
Step-by-step explanation:
Difference of two minus three = 2-3
Quotient of b divided by the difference of two minus three is
Therefore, the required expression is

We solve the equation (1/6)x + 14 = (3/4)x, where x is the number of gallons;
We have 2x/12 + 168/12 = 9x/12;
2x + 168 = 9x;
168 = 7x;
x = 168 ÷ 7;
x = 24 gallons;
