Hello!

Could I ask you a big favor?

I need help .

I have :

2x + [24-2 (y)] = 20

I tried to use Equation Solver here:

http://www.numberempire.com/equationsolver.php?function=2x+%2B+%5B24-2+%28y%29%5D+%3D+20&var=y&answers=

And I've got: y = x+2

It's the right answer, textbook shows me the same.

But I want to understand the way to solve it.

Please give me step by step explanation.

Thanks in advance!
