Question 596169
"twice the sum of a number and 4 is equal to 22" translates to {{{2(n+4)=22}}} where n is the unknown number. Let's solve for n.


{{{2(n+4)=22}}} Start with the given equation.



{{{2n+8=22}}} Distribute.



{{{2n=22-8}}} Subtract {{{8}}} from both sides.



{{{2n=14}}} Combine like terms on the right side.



{{{n=(14)/(2)}}} Divide both sides by {{{2}}} to isolate {{{n}}}.



{{{n=7}}} Reduce.

Answer:


So the solution is {{{n=7}}}
