Answer:
hi
Step-by-step explanation:
Given:
A solution of 60% fertilizer is to be mixed with a solution of 21% fertilizer to form 234 liters of a 43% solution.
To find:
The quantity of the 60% solution in the mixture.
Solution:
Let x be the quantity of the 60% solution and y be the quantity of the 21% solution.
Quantity of mixture is 234. So,

...(i)
The mixture has 43% fertilizer. So,

Multiply both sides by 100.
...(ii)
Using (i) and (ii), we get




Divide both sides by -39.


Putting this value in (i), we get


Therefore, 132 liters of the 60% solution must be used.
So firstly, you want to multiply both sides by (x-2)(x+2) since it is the LCM, or lowest common multiplier. Your equation will look like this: 
Next, you can cancel out the denominators on 3/x+2 and 4/x-2 on the left side: 
Next, foil: 
Next, combine like terms: 
Next, add x + 14 on both sides: 
Next, replace x with -5x + 6x: 
Next, factor 5x^2-5x and 6x-6 separately. Make sure that both factors have the same quantity within the parentheses: 
With this, we can rewrite it as
From here, we solve for x in (5x+6) and (x-1) separately and setting them to zero.


In short, x = -1.2, 1.
