Question 30744
(x+5)/5=(x-4)/8

cross multiply and we get 

8(x+5) = 5(x-4)

solving brackets would give ...

8x + 40 = 5x - 20

put together like variables from both sides and we get..

8x - 5x = -20 - 40

3x = -60

divide both sides by 3 and we get...

x = -20

Now if you want to  verify you answer ,,,you can put the values of x in the equation and if you get LHS=RHS,,,this means that you answer is correct..

hope this will help you
