Answers.

(3x-4)+(7x+9)

Rewrite the expression by removing parenthesis as follows...

3x - 4 + 7x + 9

Now collect the like terms together.....

3x + 7x - 4 + 9

10x + 5 , which is the simplified form.
==================================================================

(4x-9y)-(-6x+8y)

==> 4x - 9y + 6x - 8y
Now collect the like terms together...

==> 4x + 6x - 9y - 8y

==> 10x - 17y
===============================================================

-5x - 9x - 2x = -14x - 2x = -16x
===============================================================

Hope you understood.
