-4 + 2x = 4x + 6
Subtract 2x from both sides
-4 + 2x - 2x = 4x - 2x + 6
-4 = 2x + 6
Subtract 6 from both sides
-4 - 6 = 2x +6 - 6
-10 = 2x
Divide both sides by 2
-10/2 = 2x/2
-5 = x

-4 + 2x = 4x + 6
-10 = 2x
-5 = x
therefore, x = -5

-4+2x=4x+6
move x's to same side by subracting 2x and move 6 to other side by subtracting 6.
so
-10=2x
-5=x

We want to get x all by itself. So first subtract 2x from both sides. This gets rid of the x term on the left
-4 = 2x + 6
And now to get the "2x" by itself, subtract 6 from both sides
-10 = 2x
Finally, to get x alone, divide both sides by 2.
-5 = x
So that's the solution: x = -5.

-4+2x=4x+6
2x=4x+10
2x-4x=10
-2x=10
x= - 5
