How do you solve one step equation?

Answer 1

I guess the easiest way to show you is by using an example:

1) 5=x-2

Okay, we need to keep both sides of the equal sign EQUAL. To do this, add 2 from 2 (you always add/subract the same value as the number you are adding from,) and evidently you get x. Now, to keep the sides equal, we need to subtract 2 from the 5. The reason we add fom the five and not x is because x is a variable, and 2 is a number... You cannot add from different terms. Anyways, your equation should look something like this:

1) 5=x- 2

+2 +2

_________

7=x

Since all you have is a three and an equal sign left over, your answer is 7 = x, or more properly x = 7. I hope I've helped!
