(x + y )(n + 1 ) - 3 (n + 1 ) = a ( a + b ) - b ( a + b ) = m (2a + b ) + p ( 2a + b ) = ( a2
+ 1 ) - b (a2 + 1 ) = a (2 + x ) - ( 2 + x ) = (a + 1 )(a - 1 ) - 2 ( a - 1 ) = (2x + 3 )( 3 - r )
- (2x - 5 )( 3 - r ) = 11. a (x+1) + b (x+1) = 12. x (a+1) - 3 (a+1) = 13. 2 (x-1) + y (x-1)
= 14. m (a-b) + (a-b) = 15. 2x (n-1) + 3y (n-1) = 16. a (n+2) + n+2 = 17. x (a+1) ...
