This is easy. Just to help you, and not necessarily cheat, it already tells you what the missing numbers are. So if a is 3, you can just go 2 x 3 x 3. when numbers are together like this, or letters, you multiply. (3(4), or 2a) You do that with the rest of your equations, and you will get your answers. But if this isn't what you having a problem with, then just tell me.
(4t+8)+t=414 Blah blah, I don't feel like doing work so I'll just use process of deduction and put the right answer here 34=17(Tulip number) 380=76(Rose number) 380+34=414 76 roses and seventeen tulips I hope I helped!!
