Ronda,
           You would begin by clearing out your parenthesis. You would multiply both 5w & x by -4 and then you would multiply both x & 3w by 5 this would look like this:
 
(-4)(5w) + (-4)(x) + (5)(x) - (5)(3w).
 
After performing theses operations you would combine your like terms so that you would end up with a certain number x plus or minus a certain number w.
 
Please let me know what you come up with
Hi Ronda;
-4(5w+x)+5(x-3w)
Distribute the -4 within its parentheses.
Distribute the +5 within its parentheses.
-20w-4x+5x-15w
Combine like terms...
-20w-15w=-35w
-4x+5x=1x=x
-35w+x
