Solution
For this case we have the following equation given:
And we can distribute the terms first ans we got:
[tex]6n-12-\frac{1}{4}n=\frac{3}{4}n+3[/tex]Then we can aggrupate the terms like this:
[tex]6n-\frac{1}{4}n-\frac{3}{4}n=12+3[/tex]Then we can solve for n like this:
[tex]6n-1n=15[/tex]5n =15
n = 15/5= 3
