For this problem, to be able to solve for n, we can use cross -multification to be able to solve.
00:07
But first, we notice that there are ends in the denominator, so we need to see if there's any exclusions.
00:14
To start, let's do the 4n minus 1.
00:17
So we will set that equal to 0 to see if there is any exclusion to our answers.
00:26
Our first step will be to add over a 1.
00:30
So this will equal 4n equals 1 and divide it over a 4.
00:45
So n cannot equal 1 fourth.
00:54
For our next denominator, we have 2n minus 5.
00:59
So we will do 2n minus 5, set it equal to 0.
01:06
So if we add 5 to both sides, we will get 2n equals 5.
01:15
And then if we divide both sides by two, we get n cannot equal 5 over 2.
01:29
So these two answers will be excluded from our solutions.
01:36
To start, we will want to cross multiply.
01:40
So i am going to cross multiply first the 3 and the 2 and minus 5...
