Question

12-9+c=12 what value of c makes the equation true​

Answer 1

Hey there!

• $\bold{12-9+c=12}$
• Firstly, subtract by $\bold{12}$ on each of your sides
• $\bold{12-9+c-12=12-12}$
• $\bold{Cancel:12-12}$ because it gives you the result of $\bold{Keep:12-9+c-12}$ because it helps us solve for the value of $\bold{0}$
• $\bold{-9+c=0}$
• Now, we have to subtract by the number $\bold{9}$
• $\bold{-9+c+9=0+9}$
• $\bold{Cancel:-9+9}$ because it gives you the  result of $\bold{0}$
• $\bold{Keep:0+9}$  because us the value of $\bold{c}$
• $\boxed{\boxed{\bold{Answer:c=9}}}\checkmark$

Good luck on your assignment and enjoy your day!

Answer 2

Hello!

Answer:

$\boxed{C=9}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

First, you subtract by 12 from both sides of an equation.

$12-9+c-12=12-12$

Simplify by equation.

$-9+c=0$

Then, you add by 9 from both sides of an equation.

$-9+c+9=0+9$

Add by the numbers from left to right.

$0+9=9$

$\boxed{C=9}$, which is our final answer.

Hope this helps!

Thanks!
