C 9
D 12

Answer 1

Hey there!

`\large\boxed{c=9}`

12 - 9 + c = 12

Combine like terms.

3 + c = 12

Subtract 3 from each side of the equation.

3 - 3 + c = 12 - 3

c = 9

Check:

12 - 9 + c = 12

12 - 9 + 9 = 12

3 + 9 = 12

12 = 12

Hope this helps!

Answer 2

Answer:9

Explanation:

12-9=3 12-3=9 3+9=12

So C=9
