Question

how do you solve these

1. 7d-2+5=20

2. 4x-10x=28

3. -4x-10x+28

4. 8y-3y+6= -10

5. 9+4w-6=12

6. 9w+4-6=12

7.18m-6-m=-16

8. -6r-r-13=-18

Answer 1

1.
7d-2+5=20
7d = 20 + 2 - 5
7d = 17
d = 17/7
d = 2 3/7


2.
4x-10x=28
-6x = 28
x = 28/6
x = 4 4/6 = 4 2/3

Follow that pattern for the rest of your problems.

Answer 2

The answer to number two should be:
- 4 2/3
