Instructions: Write an equation using the variable n.
Problem: One-third of a painting job takes 24 hours. How long will it take to complete the entire job?
My thought: 24x3=72 so, n=72 ? I apologize I am new to algebra I'm sure the answer must be much more complicated?

2. Tough call. It is not perfectly clear what is wanted.

You have already 24 * 3 = 72

You can do this: n * 3 = 72, where n = 24

You can do this: 24 * n = 72, where n = 3

You can do this: 24 * 3 = n, where n = 72

It's kind of bad form to use the same variable for three different purposes, but there it is.

The instruction above tells you to use the symbol n to represent the unknown number of hours that it takes to complete the entire job.

Hence, the expression that represents one-third of this unknown number of hours is:
n/3

Because we're told that one-third of n is 24 hours, the requested equation is:
n/3 = 24

Solve for n.

This is certainly nothing for which anybody needs to apologize.

5. [2 + 3 = 5]
Teacher replaces the 3 with letter x:
2 + x = 5
Then gives that equation to you and asks you to solve for x.

Look at Algebra that way at start: a sort of hunt/puzzle:
do not get scared off because it's called Algebra.
Believe it or not, Algebra is actually FUN

Actually, there doesn't appear to be anywhere in that problem that says you need to solve the equation- just write the equation.

7. I don't think so, Junior Member HallsofIvy.

The OP states: "How long will it take to complete the entire job?"

We answer this question by solving the requested equation for n.
