The quotient of a number and 2 is the same as the difference of the number doubled and 3. What is the number?
The first thing we need to do is derive expressions from the given problem.
"The quotient of a number and 2", can be written as:
And "the difference of a number doubled and 3" as:
In the problem, it states that both of these expressions have the same value.
Knowing this, we need only set these expressions equal to each other:
And we solve for
