Answer:
53.
Step-by-step explanation:
The answer is 43.
n - 12 = 41
Algebraically, 12 needs to be added to both sides of the equation in order to isolate the variable (in this case, n). The 12 needs to be <u>added</u> because the opposite of -12 is +12. (n - 12 = 41)
Now the equation looks like this:
n - 12 = 41
+ 12 + 12
The 12s on the left side cancel each other out (since -12 + 12 = 0)
Now all that's left to do is 41 + 12.
41 + 12 = 53.
n = 53
Now, as for the check step, we place the digit 53 into the place of the variable. Since 53 - 12 = 41 does equal 41, the equation was solved correctly.
