b) (5a - 11b + 4 ) +(7a +8b) - (7b - 8)= 5a-11b+4+7a+8b=12a-3b+11
d) (2x -7) - (3y + 5x) + (15z - 4y) - (-3x + 11z) +7=2x-7-3y-5x+15z-
4y=-3x-7+y-5x+15z
Sory bym zrobil wszystkie bo mialem to dawno ale czasu nie mam wielkie sory
(5a - 11b + 4 ) +(7a +8b) - (7b - 8)= 5a - 11b +4 + 7a + 8b - 7b + 8 = 12a - 10b + 12
(3x²-4)-(18-4x²)+(15x²+7x - 15)-25= 3x² - 4 -18 + 4x² + 15x² + 7x -15 - 25 = 22x² + 7x - 62
(2x -7) - (3y + 5x) + (15z - 4y) - (-3x + 11z) +7= 2x - 7 - 3y - 5x + 15z - 4y + 3x - 11z +7 = - 7y + 4z
Mam nadzieję,że choć troszkę pomogłam

f) -(2a - 3b +5) + ( 4a -7 + 3) - (- 3a -2b -1)=-2a+3b-5+4a-7+3-3a+2b+1=5b-a-11
g) (4a + 2b -7) - (a -3b -4) - (2a -b -3)=4a+2b-7-a+3b+4-2a+b+3=6b-a
