-89x-x+41x+128 = -49х + 128 = 128 - 49х
-58x-162x-29x+x = -249х + х = -248х
-5a+8(1+3a) = -5а + 8 + 24а = 8 + 19а
-9c-7(1-2c) = -9с - 7 + 14с = 5с - 7
3b-6(2-4b) = 3b - 12 + 24b = 27b - 12
-6(3+x)+8(2-x) = -18 - 6х + 16 - 8х = -2 - 14х

-89х-х+41х+128=-49х+128
-58х-162х-29х+х=-220-29х+х=-248х
-5а+8(1+3а)=-5а+8+24а=32а +8
-9с-7(1-2с)=-9с-7+14с=5с-7
