The answer of this problem is r= -28
If you want me to show work for this problem tell me on this comment okay ^^ and I'll edit my answer for you 
-3(14+5r)-2r=-14(r+3)
distributivity
(-3x14)+(-3x5r)-2r=(-14xr)+(-14x3)
-42-15r-2r=-14r-42
-42-17r=-14r-42
-42-17r+14r=-14r-42+14r
-42-3r=-42
-42-3r+42=-42+42
-3r=0
-3r/-3=0/-3  so r=0
