The original number is Will adding 7 to each answer always result in the original number? Explain. O A. Yes, let x be the number and a be the answer. Then the following is true. -[-(x + −10) + −3] = a -[-x+ 10 + −3] = a -(-x + 7) = a x + 7 = a x = a +7 B. No, let x be the number and a be the answer. Then the following is true. -[-(x+10)+ - 3] = a -[-x + 10 +3] = a -(-x+13) = a x+13=a x = a + 13
