Feedzeh wrote Ok so if they are saying a=9 It means every time on the equation you see (a) Sub in the 9ine instead!
Eg:
4a x 5a a=2
That means
4(2) x 5(2)
Then just multiply it out 8 x 10 = 80!
Hope this help some rep would be nice!

Um the answer to his is 31 though

i think it just a example hes doing

Thanks guys what do i do if its something like 8(a+5)

Yh I understand But it is better to give him a template to work it out then give him the answer!
I know its 31

It's 31. This is really simple. Just substitute a for 9.

Really ? What year are you in ?

That answers 31 its so easy!

Same thing man just sub it in and add it lets say a=4
it means 8(4+5) = 8(9) =72

3a+4 when a=9
so
3x9=27
+4=31
