I'm assuming you want to solve this equation: 3x-39+x+52-25=180.  First, let's rewrite this so we know where the negatives are, and we can just add.  3x+(-39)+x+52+(-25)=180.  Note that x=1x.  Next, we can combine like terms: that is, terms with the same coefficient.  3x and x both have x in them, so they are like terms.  -39, 52, and -25 are also like terms because they have no coefficients.  3x+1x=4x, and -39+52+(-25)=38.  So, 4x-12=180.  Finally, let's solve for x.  4x-12+12=180+12.  4x=192.  4x/4=192/4.  x=48 degrees.

Answer: x=48 degrees
