Tìm x, biết: 4.(x- 5)-3.(x+7) =5.(-4)

Bài 1 :
2, 4.(x-5)-3.(x+7)=5.(-4)
3,  5. (4-x) -7 . (-x +2)=4-9+3
4, -3 . (x-5) +6 . ( x+2)=9
5,  4x-5.(-3+x)=7
6,  5.(x-3)-2.(x+6)=9
7, 5.(x-7)+10.(3-x)=20
8, -4.(x+1)+8.(x-3)=24
9, 7. (5-x)+5 . ( x-2) =15
10, 4. ( x-1)-3.( x-2) =-|-5|
11, 5. (3- 2x)+5. (x-4)= 6-4x
