Answer 2

Answer:

First number =28 ,Second number =32

Step-by-step explanation:

In context to the question it is asked to find the value of X

Here some data is given as follows

Ratio of two numbers=7:8

4 is added  to both numbers  then ratio is =8:9

Let us assume first no is =7 x

Second number is =8 x

Now make the equation as follows

$=\frac{7 x+4}{8 x+4} =\frac{8}{9}$

Then simply cross multiply the equation for getting the answer

$9(7 x+4) = 8(8 x+4)\\63 x +36 =64 x +32\\=64 x-63 x=36 -32\\1 x=4\\x=\frac{4}{1} \\x=4$

After finding the value of x putting this  value  of x in the ratio we get the original value of the numbers

first  Number =7 x

      $=7\times 4\\=28$

Now

Second  Number =8 x

                        $=8\times 4\\=32$

So first Number  is 28 and second Number is 32
