With the following:
a. 3x+7=-x-1
b. 1-2x+5=4x-3
c. 4x-2+x=-2+2x
d. 3x-4+1=2x-5+5x
solve for x
( show work)

Answer and step-by-step explanation:

a. 3x+7=-x-1

Bring x into 1 side and the other number into another side, we got:

3x + x = -1 - 7

4x = -8

Divide both side by 4:

4x / 4 = -8/4

x = -2

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

1 + 5 + 3 = 4x + 2x

9 = 6x

Divide both side by 6:

x = 9/6 = 3/2 or 1.5

c. 4x-2+x=-2+2x

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

3x = 0

x = 0

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

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

-10x = -2

x = -2/-10

x = 2/10 = 1/5 or 0.2
