Question 30738
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
