Alright so we need to get rid of the 1/5, how do you undo fractions?

kise_ryouta · Answer

divide right

benji · Answer

If you think about it, a fraction is dividing already it is 1 divided by 5.

benji · Answer

We would multiply by the denominater to get rid of it so $$(5)\frac{ 1 }{ 5}(25-5a)=(5)(4-a)$$

benji · Answer

So the 6 and 1/5 cancel and we are left with $$25-5a=(5)(4-a)$$So what do we do next?

benji · Answer

You can factor out a 5 and you would have $$\frac{ 1 }{ 5 }5(5-a)=4-a$$and then$$5-a=4-a$$

jhonyy9 · Answer

exactly @Benji and in this way you can solve it for ,,a" very very easy
