[Blindmath] Solving systems by Graphing

[Pranav Lal via Blindmath]

Susan,
<snip definition of a system of equations from a 1945 Intermediate Algebra
book. 
"When two or more equations are considered together, and a common solution 
for them is desired, this is called a system of equations."
PL] Oh, I wish I knew this definition when I was doing this in
middle-school. That was so many years ago! My math textbook at that time
defined two equations in terms of graphs or something silly!
