Rewrite in simplest terms:-(−9q+3r)+6r−2(−4r+9q)
The expression -(−9q+3r)+6r−2(−4r+9q) can be simplified as follows:
-(-9q+3r) + 6r - 2(-4r+9q)
This can be further simplified to:
9q - 3r + 6r -2(-4r) + 2(9q)
Simplifying -2(-4r) gives us 8r, and 2(9q) gives us 18q.
So, the final simplified expression is:
9q - 3r + 6r + 8r + 18q
