-4(x - 4) = 6x + 36?
-4x + 16 = 6x + 36
-10x + 16 = 36
-10x = 20
x = 20/-10
x = -2

Simple algebra.
1) Expand the brackets:
-4x + 16 = 6x + 36
2) Gather all the x terms to one side and the units to the other.
-4x - 6x = 36 - 16
-10x = 20
3) Solve for x
x = 20/(-10) = -2

Step One - Distribute = -4x+16=6x+36
Step Two - Get variables on one side = -4x - 6x + 16 =36
Step Three - Combine like terms = -10x + 16 = 36
Step Four - Isolate Variable = -10x = 20
Step Five - Solve for x :: X= -2

Whoah, deja vu. I take it you want this solved for x.
-4(x - 4) = 6x + 36
-4x + 16 = 6x + 36 *
16 = 10x + 36
-20 = 10x
x = -20/10 = -2
* - some people who are getting "5.2" are doing this step wrong.

-4(x-4) = 6x + 36
-4x -16 = 6x +36
-10x =36+16
10x = -52
x = -5.2

-4x + 16 = 6x + 36
16 - 36 = 6x + 4x
-20 = 10 x
-2 = x
x = -2

-4(x-4) = 6x +36
Distribute
-4x + 16 = 6x +36
X's alone
-4x - 6x + 16 - 16 = 6x - 6x +36 - 16
Simlify
-10x = 20
Divide
(-10x)/-10 = 20/-10
And
x = -2

1) -4(x - 4) = 6x + 36
Simplify and solve.
2) -4x + 16 = 6x + 36
3) -10x = 20
4) (divide by -10) x = -2
hope it helped!
