First, use the distributive property:
-6(4x+1)+7x+9(x-3)=4
-24x+-6+7x+9x-27=4
Then, combine the like terms together. Let's start with the terms that have x in them:
-17x+-6+7x+9x-27=4
-17x+-6+16x-27=4
-x+-6-27=4
After that, you comine the other terms (this time the normal numbers):
-x+-33=4
Now that all the like terms are combined, we need to simplify. Start by adding 33 to each side:
-x=37
This may seem like it is the answer, but you still aren't finished. You can never have a negative variable. To make this positive, you must divide by -1 on each side, which gives you the final answer of:
x=-37
Hope this helps!

OK, first get rid of the parentheses: -24x -6 +7x +9x -27 = 4. Then add 27 and 6 to each side: -24x +7x +9x = 4 + 27 + 6. Now combine the terms: -8x = 37. Finally, divide both sides by -8: x = -37/8 = -4 5/8

-6(4x + 1) + 7x + 9(x - 3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-8x = 37
x = -37/8

-6(4x + 1) + 7x + 9(x - 3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-8x - 33 = 4
-8x = 37
x = - 37 / 8 or -4 5/8 or -4.625

Distributive property:
-24x-6+7x+9x-27=4
Combine like terms:
-8x-33=4
Add 33 to both sides:
-8x=37
x=-37/8
Check:
-8(-37/8)-33=4
37-33=4
4=4
