solve for x? solving two step equations?

1.
8x - 2 = -9 + 7x
8x - 7x = -9 + 2
x = -7

2.
p - 1 = 5p + 3p - 8
p - 5p - 3p = -8 + 1
-7p = -7
p = -7/(-7)
p = 1

3.
5n + 34 = -2 (1 - 7n)
5n + 34 = -2 + 14n
5n - 14n = -2 - 34
-9n = -36
n = -36/(-9)
n = 4

4.
-18 - 6k = 6 (1 + 3k)
-18 - 6k = 6 + 18k
-6k - 18k = 6 + 18
-24k = 24
k = 24/(-24)
k = -1

1. x = - 7.

2. p = 1.

3. n = 4.

4. k = - 1.

1.
8x - 2 = -9 + 7x
x = -7
2.
p - 1 = 5p + 3p - 8
p = 1
3.
5n + 34 = -2 (1 - 7n)
n = 4
4.
-18 - 6k = 6 (1 + 3k)
k = -1

1
8x - 2 = - 9 + 7x
2x = - 7
x = - 5/2

2.
p - 1 = 8p - 8
7 = 7p
p = 1

3.
5n + 14 = - 2 + 14n
16 = 9 n
n = 16/9

4.
- 18 - 6k = 6 + 18 k
- 24 = 24 k
k = - 1
