Find the solution by looking at graphs
This is probably the easiest topic we'll cover all year! :-)
When a system of equations is graphed, the solution is the point where the two lines intersect.
That's literally it.

Number your paper from 1 to 18. Every answer should be in the form (x,y).

Keep in mind...there are some special cases when the lines don't intersect at exactly one point...
Is the given value a solution?

Solve a system by substitution (with an isolated variable)
Click HERE to check out Cool Math's description of solving systems by substitution. Their explanations are REALLY good, and they color code! :-)
*** Start at 1:39 and watch until 3:25
Solve a system by substitution AKA f(x) = g(x) or Eq1 = Eq2
*** Start at 2:13

Solve a system by elimination
We call it "elimination"...they call it "linear combination"...same thing!

Elimination: Practice Problems (With Answers!)
Only focus on Problems 1-16. The solutions are on the 3rd and 4th pages.
# 1-4 will cancel as is, no transformations are needed.
# 5-8 require a flip the signs transformation
# 9-16 require a complete transformation, either positive or negative
