Answer:

They are not equivalent.

Look at the explanation section to know why and check out the attachment.

Explanation:

One way is to check it graphically. I will put in the equations into a graphing calculator to show you that these expressions are not equivalent. Please see the attachment.

The other way is to check it algebraically.

First combine like terms in the second expression.

6x-4-x=5x-4

7x-4 and 5x-4 are not equivalent.

Hope this helps!

If not, I am sorry.
