Free_Kalibri [48]

The number of stamps with penny in terms of x is $\frac{x}{6}$

Solution:

Given that,

Ryan has x stamps in his collection

Number of stamps of Ryan = x stamps

Let the stamps with penny be "a"

Ryan has 6 times as many stamps as penny

Therefore,

Number of stamps in Ryan = 6 times as many stamps as penny

$\text{Number of stamps in Ryan } = 6 \times a\\\\x = 6a\\\\a = \frac{x}{6}$

Thus number of stamps with penny in terms of x is $\frac{x}{6}$

$9(x +3) = 3(3x + 6) + 9$

$9x + 27 = 9x + 18 + 9$

$9x + 27 = 9x + 27$

The two sides of this equation are exactly the same, so the above equation holds for any value of x , thus we have infinite solution for it.
