Direct and literal translation of words to Math is THIS : find positive solution to equation x =+ 2. To solve it, multiply both sides by x and then simplify step by step x^2 = 3 + 2x x^2 - 2x - 3 = 0 (x-3)*(x+1) = 0. The two roots are x= 3 and x= -1; but only positive x= 3 satisfies the problem's condition. ANSWER. The number is 3.
