The answer is 7.02 because you subtract 14.54 over to 7.52 and get a negative -7.02 but you can´t have a -n so you have to divide -7.02/-n and it goes postive so n=7.02 Hope That Helps :)
If you are trying to figure what the value of n is, it would be 7.02 because you have to isolate the variable (n) by subtracting 14.54 on both sides giving you -n=-7.02 and then you divide both sides with -1 because it is known that a variable by itself is multiplied by one, -1 in this case because the negative sign was placed in front of the variable.
