А) 4(1,5x-3)-5,5x=10
6x - 12 - 5.5x = 10
0.5x - 12 = 10
0.5x = 22
x = 44

б) (x+1)(x+2)-x^2=5x+4
x^2 + 3x + 2 - x^2 = 5x + 4
3x + 2 = 5x + 4
2 = 2x + 4
-2 = 2x
x = -1

в) x(x-1)-x(x-3)=12
x^2 - x - x^2 + 3x = 12
2x = 12
x = 6

г) 0.6x = 0.3-3(x+2.5)
0.6x = 0.3 - 3x - 7.5
0.6x + 3x = -7.5 + 0.3
3.6x = -7.2
x = -2

д) 3(x-1) = 3x - 4(8x+1)
3x - 3 = 3x - 32x - 4
3x - 3 = -29x - 4
29x = -1
x = -1/29

е) 8(x-8) + 2(1-2x) = 11
8x - 64 + 2 - 4x = 11
4x - 62 = 11
4x = 73
x = 73/4

ж) (x-4)^2 = x^2 - 16
x^2 - 8x + 16 = x^2 - 16
-8x + 16 = -16
-8x = -32
x = 4

з) (x+1)^2 = x^2 + 1
x^2 + 2x + 1 = x^2 + 1
2x + 1 = 1
2x = 0
x = 0
