Answer 1

Answer:

$n=\frac{3f-8}{10}$

Step-by-step explanation:

So we have the equation:

$\frac{3}{4}f-\frac{5}{2}n=2$

First, remove all the fractions by multiplying by the LCM of the denominator.

The LCM of 4 and 2 is 4. Thus:

$4(\frac{3}{4}f-\frac{5}{2}n)=4(2)$

Distribute:

$4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)$

Simplify:

$3f-10n=8$

Subtract 3f from both sides:

$(3f-10n)-3f=(8)-3f\\-10n=8-3f$

Divide both sides by -10:

$n=\frac{8-3f}{-10}$

Divide by -1:

$n=\frac{3f-8}{10}$

And this is our answer :)

Answer 2

• Answer:

n = (3f - 8)/10

• Step-by-step explanation:

3f/4 - ²⁾5n/2 = ⁴⁾2

3f - 10n = 8

3f - 8 = 10n

n = (3f - 8)/10
