1.) 6s + (3s-2) = 14 2.) 8y - (7y-142) = 51 3.) (6x+1) - (3-2x) = 14 4.) (6-2c) + 4=-5c-3 5.) (10x-3) + (14x-4) = 8 - (15-22x) 6.) (7-10k) - (8-8k) + (10k+6) = -8

Решим выражения:

1.) 6s + (3s - 2) = 14;

6s + 3s = 14 + 2;

9s = 16;

s = 16/9 = 1 7/9.

2.) 8y - (7y - 142) = 51;

8y - 7y = 51 - 142;

y = - 91.

3.) (6x + 1) - (3 - 2x) = 14;

6x + 2x = 14 - 1 + 3;

8x = 16;

x = 2.

4.) (6 - 2c) + 4 = - 5c - 3;

5c - 2c = - (6 + 3 + 4);

3c = - 13;

c = - 13/3 = - 4 1/3.

5.) (10x - 3) + (14x - 4) = 8 - (15 - 22x);

10x + 14x - 22x = 3 + 4 + 8 - 15;

2x = 0;

x = 0.

6.) (7 - 10k) - (8 - 8k) + (10k + 6) = - 8;

8k - 10k + 10k = 8 - 7 - 6 - 8;

8k = - 13;

k = - 13/8 = - 1 5/8.
