Final answer:
To solve for l in the equation 3/4n + 5/2l = 2, subtract 3/4n from both sides, then multiply by 2/5 to isolate and solve for l, resulting in l = 4/5 - 3/5n.
Step-by-step explanation:
The original equation provided by the student is: 3/4n + 5/2l = 2. To solve for l, we first need to isolate l on one side of the equation. To do this, we can subtract 3/4n from both sides of the equation:
5/2l = 2 - 3/4n
Next, we multiply both sides by 2/5 to solve for l:
l = (2 - 3/4n) * (2/5)
l = 4/5 - 3/5n
Now we have the expression for l in terms of n. Note that the provided reference material seems to be unrelated to solving the provided equation, so it has been disregarded and a direct algebraic solution is given instead.
