You can put this solution on YOUR website! First off, you have to convert "Twenty more than twice a number is 52" into an algebraic equation. To do this, simply break the question apart:
"Twenty more than" means "20+", because "more than" generally is telling you to add.
"Twice a number" means "2*n." The reasoning behind this is that "a number" typically means a variable, and we'll use n in this case (Though it doesn't really matter which variable you pick.) And twice obviously means "2 times."
"is 52" translates neatly into "=52," because "is" means the same as "equals"
Thus, we arrive at the equation "20+2*n=52"
Since we have one equation and one variable, it should be pretty easy to solve:
20+2*n=52
Subtract 20 from both sides, so we can have the variable alone.
20+2*n-20=52-20
2*n=32
Now, we will divide both sides by two to find n's solution.
n=16
