"twice the sum of a number and 4 is equal to 22" translates to 2%28n%2B4%29=22 where n is the unknown number. Let's solve for n.

2%28n%2B4%29=22 Start with the given equation.


2n%2B8=22 Distribute.


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


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


n=%2814%29%2F%282%29 Divide both sides by 2 to isolate n.


n=7 Reduce.

Answer:

So the solution is n=7
