Решите уравнения:
1) -4 * (-z +7) = z +17
2) c - 32 = (c +8) * (-7)
3) 12 - 2 * (k+3) = 26
4) - 3,2n +4,8 = -2 * (1,2n +2,4)
5) - 5 * (0,8z - 1,2) = -z + 7,2
Заранее спасибо.

1) -4 * (-z +7) = z +17
-4z-28=z+17
-4z-z=17+28
-5z=45
z=-45/5
z=-9
2) c - 32 = (c +8) * (-7)
c-32=-7c-56
c+7c=-56+32
8c=-24
c=-24/8
c=-3
3) 12 - 2 * (k+3) = 26
12-2k-6=26
-2k=26+6-12
-2k=20
k=-20/2
k=-10
4) - 3,2n +4,8 = -2 * (1,2n +2,4)
-3.2n+4.8=-2.4n-4.8
-3.2n+2.4n=-4.8-4.8
-0.8n=-9.6
n=9.6/0.8
n=12
5) - 5 * (0,8z - 1,2) = -z + 7,2
-4z+6=
-z + 7,2
-4z+z=7.2-6
-3z=1.2
z=-1.2/3
z=-0.4
