A would be the closest estimate
See my previous answer to this same question. the vertical angles have to be right angles
To eliminate the fraction, we multiply by 4
<h3>How to eliminate the fractions?</h3>
The equation is given as:
-3/4m-1/2=2+1/4m
Rewrite properly as:

The denominators of the above fractions are 2 and 4
The LCM of 2 and 4 is 4
So, we multiply through by 4.
This gives
-3m - 2 = 8 + m
Hence, to eliminate the fraction, we multiply by 4

whatever the amounts of "x" and "y" are, they must add up to 5Liters
thus x + y = 5
and whatever the concentrated quantity is in each, they must add up to (5)(0.14)
notice, that we use the decimal notation for the amount of juice concentration, that is, 15% is just 15/100 or 0.15, and 14% is just 14/100 or 0.14 and so on, recall that "whatever% of something" is just (whatever/100)*something
thus

solve for "x", to see how much of the 15% juice will be needed
what about "y"? well, y = 5 - x
