Solve for n:
3/4f-5/2n=2
n=

Answer 1

• Answer:

n = (3f - 8)/10

• Explanation:

3f/4 - ²⁾5n/2 = ⁴⁾2

3f - 10n = 8

3f - 8 = 10n

n = (3f - 8)/10

Answer 2

`n=(3f-8)/(10)`

Explanation:

So we have the equation:

`(3)/(4)f-(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((3)/(4)f-(5)/(2)n)=4(2)`

Distribute:

`4((3)/(4)f})-4((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=(8-3f)/(-10)`

Divide by -1:

`n=(3f-8)/(10)`

And this is our answer :)
