Question

81+7x=81 what does x equal?

Answer 1

So to start off here is the question being asked:
81+7x=81
The first thing we are going to do is simplify both sides of the equation:
7x+81=81
Second thing to do is subtract 81 from both sides so:
7x+81−81=81−81
The final thing to do is divide both sides by 7:
7x/7=0/7
The final answer is:
x=0

I hope this helps! :)

Answer 2

The answer is x=7 because wen you subtract 81 from 81 it equals zero leving 7x or x=7
