Solution
Let the two numbers be $$8x$$ and $$13x$$.
According to the problem: $$\frac{8x + 14}{13x + 14} = \frac{2}{3}$$
Cross-multiply: $$3(8x + 14) = 2(13x + 14)$$
$$24x + 42 = 26x + 28$$
Solve for $$x$$: $$26x - 24x = 42 - 28$$
$$2x = 14 \implies x = 7$$
Calculate the numbers:
First number = $$8 \times 7 = 56$$
Second number = $$13 \times 7 = 91$$
Therefore, the numbers are 56 and 91.
