x=16
The Steps to solving this equation:
3(x+4)+2=2+5(x-4)
multiply numbers in parenthesis by 3
multiply the other numbers in parenthesis by 5
3x+12+2=2+5x-20
subtract 2 to 2
3x+12=5x-20
move terms
3x-5x=-20-12
subtract 3x to 5x, and subtract -20 to -12 but since there both negatives the equation is addition.
-2x=-32
divide Both sides by -2
x=16
