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.
