I have worked this and checked it and it does not come out true any one help me?

3x-5(3x-7)=2(x+9)+45
3x-15x-35=2x+18+45
-12x-35=2x+63
+35 +35
-12x=2x+98
-2x -2x
-10x=98
x=-98/10
x=-9 8/10
checking it i get 152 3/5 and 43 2/5
Help where did I go wrong?

    I KNOW I KNOW! When you distribute -5 to -7 in the beginning its 35 not negative 35.
