Its right, using the subtitution method I get the same answer.
First my math question....
I am asked to solve this
I followed these examples Systems of Equations - Solve by addition or subtraction and thus this occurred...
cancel the s and I'm left with
Now to solve for
I plug in into the second equation
Ok now that I have the s and the s I plug those into the first equation....right so far?!
Did I do this right?! if not, then where did I go wrong, I have a hard time with these types of equations because I can never figure out elimination/addition nor graphing!!
NOW FOR MY SECOND QUESTION what has happened to the Message: options that used to be above the text box!?
So then I would use substitution to solve this problem instead of elimination/addition?
