Question 208113
There are two ways to do this:



Method # 1



{{{n/4+3=24}}} Start with the given equation.



{{{cross(4)(n/cross(4))+4(3)=4(24)}}} Multiply EVERY term by the LCD {{{4}}} to clear out the fraction.



{{{n+12=96}}} Multiply and simplify.



{{{n=96-12}}} Subtract {{{12}}} from both sides.



{{{n=84}}} Combine like terms on the right side.

Answer:


So the solution is {{{n=84}}}

Method # 2



{{{n/4+3=24}}} Start with the given equation.



{{{n/4=24-3}}} Subtract 3 from both sides.



{{{n/4=21}}} Combine like terms.



{{{n=21*4}}} Multiply both sides by 4 to isolate 'n'.



{{{n=84}}} Multiply.

Answer:


So the solution is (once again) {{{n=84}}}
