Sue's age is one year less than half her mother's age. The sum of their ages is 71 years. If x represents Sue's age, which equation can be used to find her age?


A.3/2x-1=71


B. 2x+1=71


C.2x+2=71


D. 3x+2=71

Answer :

Option A would be your answer. We know 71 is the product. We also know that Sues age is one year less than half her mothers age. -1 comes from the problem saying one year less. We can already eliminate the other 3 options at this point.
