Question

Question: A student took a test composed of 20 question, with correct answers worth 2 points. If the student received 34 points for his grade, how many questions were correct?

I KNOW THE ANSWER IS 17 BUT PLEASE PUT IN AN EQUATION FORM

ex: (20x2)-34 = ???????

Answer 1

let x = number of questions answered correctly

set up the equation:
2x = 34

then solve:
2x = 34 *divide both sides by 2 to get x
x = 34/2 = 17

so there,, :)
