Question

Which accurately shows how to use inverse operations to find the value of a in a + 5 = 14?
14 + 5 = a
18 = a
14 + 5 = a
19 = a
14 – 5 = a
8 = a
14 – 5 = a
9 = a

Answer 1

The answer is a=9 because 14 minus 5 equals 9.

Answer 2

For this case we have the following expression:

$a + 5 = 14$

We must find the value of "a":

Subtracting 5 from both sides of the equation we have:

$a + 5-5 = 14-5$

Different signs are subtracted and the sign of the major is placed:

$a = 9$

Thus, the correct option is D.

ANswer:

$14-5 = a\\9 = a$

Option D
