Answer 2

Answer:

$\large\boxed{f=4}$

Step-by-step explanation:

To solve this problem, first you have to isolate by the variable of f on one side of the equation. So remember to solve this problem, division property of equality is divide numbers from both sides of an equation by the non-zero number doesn't change the equation at all.

Given:

5f+7=27

Solution:

First, you have to do is subtract 7 from both sides.

$\displaystyle 5f+7-7=27-7$

Solve.

$\displaystyle 27-7=20$

$\displaystyle 5f=20$

Secondly, divide by 5 from both sides.

$\displaystyle \frac{5f}{5} =\frac{20}{5}$

Solve.

$\displaystyle 20\div5=\boxed{4}$

$\large\boxed{f=4}$

As a result, the final answer is f=4.
