If the number is x, the equation is: 2x + 3 = 16
"Twice the number" means 2 * x, written in algebra as just 2x.
The sum of that and three makes 2x + 3.
And since that sum is 16, the whole equation is: 2x + 3 = 16
You could equally write it as 3 + 2x = 16, but in algebra it is normal to write the part involving x first.
