Okay, so now I can solve equations with variables on both sides easily. But now I don't know how to use the distributing property. =/ Once again, please be so kind to dumb little nut gobbler to explain step by step when solving. Thanks

Please Excuse My Dear Aunt Sally. Remember that? Order of operations is always important.
To multiply out the x+4 in parenthesis, remember to multiply everything inside seperately by whats on the outside. You'll get it.

2-3(x+4)=8 Use the distributive property
2-3x - 12=8 add 12 on both sides
2-3x= 20 subtract 2
-3x=18 divide by -3
x=-6 negative 6

2-3(x+4)=8
you distribute 3 to x+4
-3(x+4)... multiply -3 by x then 4
3x + 12
2+-3x-12 = 8
-3x - 10 = 8.. add 10 to both sides
-3x = 18.. divide by -3
x = -6

2-3(x+4)=8
multiply -3 in bracket so you Will get,
2-3x-12=8
-3x-10=8
now arrange the numbers
-3x=18
x=18/-3
x=-6

2 - 3x - 12 = 8
- 3x = 18
x = - 6
