Help..this is where I am lost!!!

Solve the following equation for the unknown, x.
(1-2x) - 3(4+5x) +6(7-8x) = 0
1-2x-3(5x+4)+6(-8x+7)=0

2x-3(5x+4)+6(-8x+7)+1=0

-2x-3*5x-3*4+6(-8x+7)+1=0
-
-2x-15x-12+6(-8x+7)+1=0
-
2x-15x+6(-8x+7)+(-11)=

(-2-15)x+6*8x)-6*7-11=0

-17x-48x+42-11=0

-65x+31=0

x=31/65

This statement is meaningless to everyone, except those who know to what the pronoun "this" refers.

You typed out every step, including the correct answer! What are you trying to ask?

You're tiring me out just looking at all your steps; who taught you that?
Can you follow this:
(1-2x) - 3(4+5x) +6(7-8x) = 0
1 - 2x - 12 - 15x + 42 - 48x = 0 : now you're just about done!
