1/5(a+3)=1/3(5-a)
Hi Sam
First I'm just going to talk about the left hand side LHS
it would be good if you realize that
1/5(a+3) = 1/5 * (a+3)/1
if you write this as an upright fraction you will be able to see that it isthe same as 1*(a+3) / (5*1) = (a+3)/5
so your equation would more usually be written as
(a+3) / 5 = (5-a) /3
Please write these fraction upright, it will make it much easier to see what is happening
3 and 5 are both denominators and they have no common factors and 3*5=15
If you multiply both sides by 15 then the denominators will cancel out and there won't be any fractions any more.
Then you just expand the brackets and solve like any other non-fraction equation.
Can you do the rest yourself?
