1) 2 - с = 5с +1.
2) -3d - 10 = 3d -6.
3) -1,6 - 0,3p = 0,9p + 0,2.
4) 4(-2z + 5) = 14 - 2(4z - 3).
5) 18 - 4y = 7(2 - y) + 6.
6) -6x + 2(6 - 3x ) = 8

3) -1.6-0.3p = 0.9p+0.2
-0,3p-0,9p = 0.2+1.6
-1.2p = 1.8
1.2p = -1,8
p =
4) 4(-2z+5) = 14-2(4z-3)
4*(-2z)+4*5=14-2*4z+2*3
-8z+20=14-8z+6
-8z+8z=14+6-20
0=0 (В таком случае z=0)
