First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59

By the Pythagorean theorem:
Factors of 20: 1; 2; 4; 5; 10; 20
Factors of 35: 1; 5; 7; 35
20 + 35 = 5 · 4 + 5 · 7 = 5 · (4 + 7)
Answer: 5 · (4 + 7)
