Noah wrote that 6+6 =12. Then he wrote that 6+6 -n =12 - n. Are his equations balanced? Explain.

Step-by-step explanation:

To check whether both equations are balanced, we will simplify

6+6 -n =12 - n

Add n to both sides of the equation using additive property

6+6-n+n = 12-n+n

6+6 +0 = 12+0

6+6 = 12 (This gives the other equation)

Since they are both equal, this shows that the equations are balanced
