4x - 2 = - 8 + 5x
4x - 2 - 4x = - 8 + 5x - 4x
- 2 = - 8 + x
- 2 + 8 = - 8 + x = + 8
6 = x
The answer is x = 6
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - -
4x - 2 = - 8 + 5x
4(6) - 2 = -8 + 5(6)
24 - 2 = - 8 + 30
22 = 22

Subtract 4x from both sides:
-2 = -8 + x
Add 8 to both sides
6 = x or x = 6
Check by inserting 6 on x's place in the equation (22 = 22, so solution is ok!)

Take the like terms to one side...
hence 8-2=5x-4x
=>6=x
x=6..

4x-2= -8+5x
combine like terms:
4x-2= -8+5x
-5x -5x
x-2 = -8
-2 -2
x=6

4x-2=-8+5x
4x-5x=-8+2
-x=-6
x=6

Add 8 to both sides and then take away 4x from both sides to get:
6=x
so x=6 is the solution.

4x-2= -8+5x
4x-5x= -8+2
-1x= -6
x= 6
