Please help me with question 19
Ksenya-84 [330]

Alright, lets get started.

Suppose the smaller integer = n

So, larger integer will be = n+2

3 times of larger integer will be = 3(n+2)

smaller integer is added into this , so

n +3 (n+2)

The result is 2 less than 5 times of smaller integer, so

5n - 2

Both are equal so,

n + 3 (n+2) = 5n - 2

n + 3n + 6 = 5n - 2

Rafael makde the mistake that he didn't put the larger integer into parenthesis like (n+2) , so three times will be 3 n + 6 as he got 3n + 2

So, the correct equation is

n +3n +6 = 5n - 2

Solving the equation

4n + 6 = 5n - 2

n = 8

So, saller integer is 8 and larger integer is 8 + 2 = 10

So, both integers are 8 and 10.  :  Answer

Hope it will help :)
