A- (4x + 3y + 1 ) + ( 6x - 2y - 9 )

B- ( 7x - 4y + 2 ) - ( 2x - 2y + 5 )

C- ( 4x - y - 1 ) - ( 9x + y + 3 )

Answer 1

A- (4x + 3y + 1 ) + ( 6x - 2y - 9 )

4x + 3y + 1 + 6x - 2y - 9 = 10x y - 8
==========================================
B- ( 7x - 4y + 2 ) - ( 2x - 2y + 5 )

7x - 4y + 2 - 2x + 2y - 5  =  5x - 2y - 3
==============================================
C- ( 4x - y - 1 ) - ( 9x + y + 3 )
4x - y - 1 - 9x - y - 3 = - 5x - 2y - 4
