Question 1116936: Helping my son with some algebra stuff. We're struggling with systems of equations. What we're struggling with mostly is 'why' you do the order of operations in the way they are done. Here's the problem:
a-6=2b
a+b=15
The questions calls for the point where the these equations cross (#,#)
Here's where we are:
Consolidating the problems: a+2b+a+b=6+15 or 2a+3b=21
Using the basic y=Mx+b to get slope.
Now have no clue where to go from here.
Appreciate the help
