1) х = 0
2) а = 
Пошаговое объяснение:
1) 15,56х+27,7х-9,3х-х = 0
32,96х = 0
х = 
х = 0
2) -8(4а+8)-(2+а)+2(8+5а) = 0
-32а - 64 - 2 - а - 16 + 10а = 0
-23а - 50 = 0
-23а = 50
а =
1) 15.56x + 27.7x - 9.3x - x = 15.56x + 27.7x - 9.3x - 1x = (15.56+27.7-9.3-1)*x = 32.96x
2) -8(4a+8) - (2+a) + 2(8+5a) = -32a - 64 - 2 - a + 16 + 10a = -23a - 50
