from the start
Algebra is basically trying to find a variable's value in an equation.
hence,
2 + x = 4.
Well it's easy to figure out. x = 2.
Because 2 + 2 = 4.
Now you can get a little more complex.
2x + 4 = 10
Well, we gotta do what every math person does.
GET x BY ITSELF. that'll make it so we can give x a value.
Well what we do first is subtract 4 FROM BOTH SIDES
2x = 6.
See how I got that I did this
2x + 4 - 4 = 10 -4
now I have 2x = 6
Now I have to get x alone.
I divide by 2 from both sides.
x = 3.
That's simple algebra.
go wikipedia it now
C'mon, you can't explain the entirety of algebra in one post. Look it up on google, I'm sure there are plenty of sites to help you out.
