How would you solve for A

5 x 3^(x+2)= A x 3^(x)

Please help me, I have loads of problems like this on my homework assignment and I just can't seem to figure it out

Well, we could divide both sides by 3^x couldn't we? We know it's never 0, so there's no division by 0 to worry about.
We'd then have (5 x 3^(x+2))/3^X = A.
Can you solve it from there?

Thank you so much
