1062-423 = 457 + n
639 = 457 + n
639 - 457 = n
182 = n
The idea is to get n on its own by taking the other numbers across, when you do they become minus numbers!!

The idea is to never lose the balance that the equal sign means.
So if you change one side you have to change the other side:
457 + n + 423 = 1062
457 + n + 423 - 423 = 1062 - 423
457 + n = 639
457 - 457 + n = 639 - 457
n = 182
I loved that kind of explanation to the equations when I was little, I'm sure she'll love it too ;)

It's 182
457 add the 423 comes to 880.
You would need 182 more to make 1062
The n just stands for number

I know this is right:
u add 457 and 423 and u get 880
then u get 1062 and substract from 880 and the answer u should get is 182

457+n+423=1062
n+880+1602
n+neg.880+880=1062+neg.880
n=182
so basically you have to combine what you can 1st, since you know 457 and 423 you can add them together that gives 880+n+1062 after that you have to get rid of the 880 so you have to add its opposite which is neg.880 BUT WHATEVER YOU CHANGE ON ONE SIDE HAS TO CHANGE ON THE OTHER SIDE TOO. so you have to add neg.880 to 1062. which leaves you with n=182

You add together 457 & 423 which equals 880. Then you subtract 880 from 1,062 and get your answer. which is 182.

That's real beginning algebra
457 + n + 423 = 1, 062
880 +n = 1,062
880 + n - 880 = 1, 062 - 880
n = 182

This is a linear equation. You want to get "n" by itself.
Whatever you do to one side of the equal sign, you do to the other.
To get "n" by itself, you must subtract 457 and 423 from that side of the equal sign, right? Do the same to the other side too. You will have your solution.
All linear equations are solved by getting the variable alone on one side. Whatever you do on that side to make it happen, do to the other side.

subtract 457 and 423 from both sides of the equation to get n alone on one side.
