(I will be using "x" as the variable name instead of the f - there is some curse word filter that gets triggered on my response and I could not save it)

first simplify each side of the equation:

-x+2+4*x=8-3*x

3*x+2=-3*x+8

then solve for x:

0*x = 6

0 = 6

this equation is never true. This result means that there are no solutions for x that would satisfy the original equation. In other words the set of solutions is empty. let me know if you have questions

Answer: The value of f is 1.

Step-by-step explanation:

Since we have given that

-f+2+4f=8-3f

We need to find the value of f :

1) First we gather the like terms together:

2) Solving the like terms

3)find the value of f.

-f+2+4f=8-3f\\\\3f+2=8-3f\\\\3f+3f=8-2\\\\6f=6\\\\f=\dfrac{6}{6}\\\\f=1

Hence, the value of f is 1.

20% of what equals 1581.01
Zepler [3.9K]
If you rewrite this phrase to be an equation, with N representing the missing number, it would be:

20% x N = 1581.01 or 0.2N = 1581.01

This equation basically says 20% of what number equals 1581.01.

To get to the answer, divide both sides by 0.2. -->

0.2N ÷ 0.2 = 1581.01 ÷ 0.2 -->
N = 1581.01/0.2
N = 7905.05
