Question 518163
{{{3(1+4n)-2(5n-3)=25}}} Start with the given equation.



{{{3+12n-10n+6=25}}} Distribute.



{{{2n+9=25}}} Combine like terms on the left side.



{{{2n=25-9}}} Subtract {{{9}}} from both sides.



{{{2n=16}}} Combine like terms on the right side.



{{{n=(16)/(2)}}} Divide both sides by {{{2}}} to isolate {{{n}}}.



{{{n=8}}} Reduce.
