Find the value of x. 4(x-7)= 3(9- 1/3x)

What is the pattern in the values as the exponents increase?

Adaylily farm sells a portion of their daylilies and allows a portion to grow and divide. the recursive formula an=1.5(an-1)-100 represents the number of daylilies, a, after n years. after the fifth year, the farmers estimate they have 2225 daylilies. how many daylilies were on the farm after the first year?

Could somebody me with this radical simplification?
