Working with Distributive property

4(7x-8)= 6(5x=10) are there 2 equal signs in this equation?
if not:
4(7x-8)=6(5x-10)
(4*7x-4*8)=(6*5x-6*10)
28x-32=30x-60
+60 +60
28x+28=30x
-28x -28x
28=2x
Multiply by 1/2 on both sides. The 2 will cancel out on the right side of the equation and divide the 28 on the left.
14=x That's the final answer if the equal sign is actually a subtraction sign.

-14(b-1)-14(-12b+12)=0

-59=-4(1+7r)-3(r+8)

8=2(n-9)+14(-11n-9)

-8(7x-11)+13(2x-3)=79

-13(6x-6)+8(1-x)=-86

-12(a-12)-6(13+3a)=6

if someone can help me with these problems it would be greatly appreciated !
