So since we are solving for x, put 20 instead of f(x):

20 = 2(x + 4)

You can distribute 2 to x and 4:

20 = 2x + 8

Subtract both sides by 8:

12 = 2x

Divide both sides by 2

6 = x

Answer:

The required expression is \frac{y}{4}-3.

The value of the expression when y=20 is 2.

Step-by-step explanation:

Consider the provided phase.

3 less than the quotient of a number y and 4

The quotient of a number y and 4 can be written as: \frac{y}{4}

Now 3 less than the quotient of a number y and 4  can be written as:

\frac{y}{4}-3

Hence, the required expression is \frac{y}{4}-3.

Now evaluate when y=20.

Substitute y=20 in above expression.

\frac{20}{4}-3

5-3

2

Hence, the value of the expression when y=20 is 2.
