Ответ:

1) 23.4 - (-5.6 + 7.4) + (-13.6 - 1) = 29.8

2) Solve for x: x - 1 + (x+2) = -4(-5 - x) - 5. Answer: x = -12

3) Solve for x: -40 • (-7x + 5) = -1600. Answer: x = 7

4) Solve for x: -9x - 8 = -8x. Answer: x = -8

5) Solve for x: 6(5 - 3x) = -8x - 7. Answer: x = -2

6) Solve for x: x - x/3 = -10/3. Answer: x = -5

7) Solve for x: 6 + (x - 7) = 20. Answer: x = 21
