Let x equal that number to be doubled.
2x + 1 = 17, now subtract 1 from each side of the
equation.
2x = 16, divide both sides of the equation by 2
x= 8

If the number is x, then double the number is 2x. Double the number, increased by one, is 2x + 1.
"Is" means "=", so the equation is 2x + 1 = 17
Can you solve by isolating the x?
