Answer:

1.) 3x + 7 = -x - 1

*collect like terms

3x + x = -1 - 7

4x = -8

x = -2

2.) 4x - 3 = 1 - 2x + 5

*collect like terms

4x + 2x = 1 + 5 + 3

6x = 9

x = 9/6

x = 3/2

3. 4x - 2 + x = 2x - 2

*collect like terms

4x + x - 2x = -2 + 2

3x = 0

x = 0/3

x = 0

4.) 3x - 4 + 1 = 5x - 5 - 2x

*collect like terms

3x - 5x + 2x = - 5 + 4 - 1

(this is a tricky one ... sorry I can't figure the answer)
