Answer 1

Ответ:

1)7+6+5-3-2-1=8

2)8+7-6:3+4-5-2-1=9

3)1+2*3+4-5-6-7+8+9=10

Answer 2

To solve the equations and make them true, you can use the following operations and parentheses:

1. 1 + 2 + 3 - 4 + 5 + 6 + 7 = 8
2. 1 + 2 + 3 + 4 - 5 + 6 + 7 + 8 = 9
3. 1 + 2 + 3 + 4 + 5 - 6 + 7 + 8 + 9 = 10

Keep in mind that there may be multiple solutions, but the above solutions are one possible arrangement of the signs and parentheses to make each equation true.
