1/7-3(3/7n-2/7)

I need help solving this problem...

The answer is 1/7n + 32/21

So we have

The first step is to distribute the –3

Next, we simplify within the parentheses. In order to do this, we must have a common denominator.

Then, we find a common denominator again and simplify.

And we're done. While it may be tempting to try to cancel 7n, this is not actually allowed. Try substituting in a non-zero number for n and you'll see why.

MIDDLE SCHOOL

Explain you can use the whole number expression 248 divided by 4 to check that your answer to exercise 2 is reasonable

248/4 = 62

to check if you are right

you do

62*4= 248

or you can do

248/62= 4

You can check in both way

to check if you are right
