Question 169738
I was unsure how to write it in the first place, I'm sorry. 
Its (7x/8) - 4=x The 7/8 is a fraction with the x on top with 7. 

There is no need to say sorry.  A lot of people do not know how to type math questions using their keyboard.  I myself made a few errors when I started about 8 years ago.

Here is your question:

(7x/8) - 4 = x

Multiply each term on both sides of the fractional equation by 8 to remove the fraction given on the left side.

After doing so, we get:

7x - 32 = 8x....This is no longer a fractional equation.  It is now called a linear equation.  The fraction is gone!

We now solve for x.

-32 = 8x - 7x

-32 = x

===================

How do we know that x = -32 is right?

We plug that answer for x back into the original equation and simplify.  If we get the same answer on both sides of the equation, then we will know that x = -32.

====================

THE PROVE:

7(-32)/8 - 4 = -32

-224/8 - 4 = -32

-28 - 4 = -32

-32 = -32...IT CHECKS!!!

Final answer: x = -32

I hope this helps.

Happy Thanksgiving.
