n = 46

$46


B.

n = 38

$38


C.


n – 19 = 65

n = 84

$84


D.


n ÷ 2 = 65

n = 130

$130

Answer 1

Your answer is A because you have to reverse operations to help you find your answer. Typically, you will subtract 19 from 65 to find your answer, but since you are looking for an equation too, you need to reverse your operations and do an equation with addition. In the end, you still need to subtract in order to find your variable's amount. So...your answer is A
