Tommy has 5 more toy cars than Billy does. Tommy has 12 toy cars. How many cars does Billy have?

Question 2 options:

A. 17 cars

B. 12 cars

C. 5 cars

D. 7 cars

suppose X for billy and Y for tommy

now

X+5=12

or, X=12-5

or, X=7

hence answer is optionD

D. 7 Cars

Step-by-step explanation:

If Tommy has 12 cars and it's 5 more than Billy

You do the inverse of addition which is Subtraction

12 - 5 = 7

In Detail:

a = Billy (Answer)

b = +5 (more or less / difference)

c = Tommy (12)

a + b = c

a + 5 = 12

Now you find out something that when you add 5 to it makes 12

You can do this by bringing the +5 to the 12 but you have to change it to a -5

So:

a + 5 = 12 turns to a = 12 -5

12 - 5 = a

7 = 12 - 5 or 12 - 5 = 7

The answer is 7
