$\longrightarrow{\green{ x\:=\:12}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$(x - 9) \frac{2}{3} = 2$

$➺ \: (x - 9) = 2 \times \frac{3}{2}$

$➺ \: x = 3 + 9$

$➺ \: x = 12$

Therefore, the value of $x$ is 12.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$(x - 9) \frac{2}{ 3} = 2$

$➺ \: (12 - 9) \frac{2}{3} = 2$

$➺ \: 3 \times \frac{2}{3} = 2$

$➺ \: 2 = 2$

$➺ \: L.H.S.=R. H. S$

Hence verified.

I=P(1+(r/n))^nt
I is the value owed
r is the rate in a decimal
n is the times compounded (annually =1, quarterly =4, monthly =12 etc.)
t is time invested
I=8000(1+(.109/1))^5x1
I=8000(1.109)^5
I=8000(<span>1.67748)
