freckles · Answer

yes there should be the value x that satisfies the equation given in the list you provided

freckles · Answer

If you don't like the fraction you could multiply both sides by 5 as a first step

freckles · Answer

if you don't care about it then just start by adding 6 on both sides

freckles · Answer

and actually i thinking getting rid of the fraction is kinda waste of time just a little

freckles · Answer

so what do you get after adding 6 on both sides ?

anonymous · Answer

The fraction negative 8 over 5 and then x = -48

freckles · Answer

$$\frac{-8}{5}x=-48$$

anonymous · Answer

Yup, that is what I got.

freckles · Answer

ok so now you need to undo some multiplication and division

anonymous · Answer

Ok. What do I undo first?

freckles · Answer

to undo the multiplication by -8 you divide both sides by -8
to undo the division by 5 you multiply both sides by 5
you can do both of these operations in one step if you just multiply both sides by 5/(-8)
which is the riciprocal of the coefficient of x

anonymous · Answer

So if I do that, the fraction will no longer be there. It will just be 5 correct?

freckles · Answer

are you multiplying both sides by 5/(-8) ?

anonymous · Answer

After divided both sides by -8.

freckles · Answer

oh okay well there will still be a 5 on bottom but not on top

freckles · Answer

on the left
