Solve and check n - 12 = 41

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 added 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.
