Thanks

Here’s the equation

simplify

5t - {7t -[5r - 2(t - 8)] + 6r} - 5r = ____

Thank you out there!!

Hi. Can we please see your work so that a helper will know exactly what you need help with? A helper will also point out why your mistakes are wrong.
I would first try to figure out what is inside [ ]. Then subtract that from 7r and then add 6r. At that point you would have what is in { }.
I would the compute 5t - { } and then subtract 5r from that.
Give it a try and post your work.
 
\(5t - \{7t -[5r - 2(t - 8)] + 6r\} - 5r \)
\(5t - \{7t -[5r - 2t +16] + 6r\} - 5r \)
\(5t - \{7t -5r + 2t -16 + 6r\} - 5r \)
\(5t - 7t +5r - 2t +16 - 6r - 5r \)
-6r-4t+16
-2(3r+2t-8) SEE HERE

Let me first say that I am the product of six years of intensive teaching using the Moore Method.
I absolutely believe in its use. But I also think it is important to when to use it and when not to.
It is necessary to get the train on the tracks to go anywhere.

Yes - but Jomo provided detailed path to the solution and the OP did not show ANY effort!

Train was only 4 hrs. late ......
