Going Crazy with these Math problems any help is appreciated?

Question

When solving for x, show all operation steps followed by results of performing those operations (i.e., show that you are adding four to both sides, then on the next line show the result of that operation). When the line you’re typing is an equation, you should not start the line with an extra leading equals sign.

1. Name the property of real numbers illustrated below. Be specific with the naming (include “of addition” or “of multiplication,” if applicable).
7 + 13 = 13 + 7

2. Combine like terms:
7x2 + 9x – 4x2 – 2 + 6x – 2x2 + 8

3. Solve for x:
8x – 2 = -2x + 18

4. Solve for x:
2(2x – 5) + 1 = x – 8 – 5x

5. Solve for x:
(x – 7)/5 – 5/2 = (x + 9)/10

6. Translate to an algebra statement; do not solve:
Three times the difference of five and a twice a number yields the same result as the same number increased by four.

Answer 1

1. associative of addition
2. 8+15x
3. x=2
4. x=11/8
5. dont understand what you wrote
6. 3(5-2x)=x+4

hope this helped

Answer 2

2. 7x2+9x-4x2-2+6x-2x2+8= x2+15x+6
3. 8x-2 = -2x+18
10x = 20
x = 2
4. 2(2x-5)+1 = x-8-5x
4x-9 = -4x - 8
8x = 1
x = 1/8
