Ayayay! i am stuck again : ) can someone me out ?

Hi Gary!

So, let's say that a reciprocal number is 1 divided by a number q. So, the reciprocal of q for example is

Now, it asks us to find also a consecutive even number.

A consecutive number is the number next to another one. Theorically this means the consecutive of q is q+1, since you add 1 to find the number next to q but.....it asks for an 'even' number and even numbers are for example 2,4,6,8 ecc., they add always 2.

So our consecutive even number would be q+2

Of course you find the reciprocal the 1 / q+2

So, let's set up the equation



Let's solve the equation by first finding the common denominator



24q ≠ 0 -> q ≠ 0 and q+2 ≠ 0 -> q ≠ -2

24q + 48 + 24q = 7q^2 + 14q

-7q^2 - 14q + 24q + 24q + 48 = 0

-7q^2 + 34x + 48 = 0

7q^2 - 34x - 48 = 0

You can factor it.

(7x+8)(x-6) = 0

7x + 8 = 0 -> 7x = -8 -> x = -8/7
x - 6 = 0 -> x = 6

We choose the positive solution.

So one number is 6, then we find the even consecutive -> 6+2 = 8

Numbers are 6 and 8
