Помогите решить уравнения!
1. 8x – 5 = x – 40
2. 9 + 13y = 35 + 26y
3. 6s+ (3s – 2) = 14
4. 8y – (7y – 142) = 51
5. (6x + 1) – (3 – 2x) = 14
6. (6 – 2c) + 4 = – 5c – 3
7. (10x–3) + (14x–4) = 8 – (15 – 22x)
8. (7–10k) – (8–8k) + (10k + 6) = – 8
9. 6y – 20 = 2(5y – 10) – 4y
10.6(1 + 5v) = 5(1 + 6v)

Ответ(ы) на вопрос:
Гость8х - 5 = х - 40
7х = 35
х = 5
9 + 13у= 35 +26у
-13у = 26
у = -2
Гость2) -13y=26
y=-2
3) 6s+3s-2=14
9s-2=14
9s=16
s=16/9
4) 8y-7y+142=51
y=142-51
y=91
5) 6x+1-3+2x=14
8x=16
x=2
