The document discusses the substitution method for solving systems of equations, which allows you to find the exact solution without graphing. It explains that the substitution method involves solving one equation for one variable and substituting that value into the other equation to solve for the remaining variable. An example problem demonstrates substituting the value of x from one equation into the other equation to solve for y.

pg. 330 # 36 to 43

2. 7.2 Substitution Method pg. 326 to 330
THIS method helps you to find the EXACT answer without graphing!!!!
REMEMBER:
You are solving systems of equations!
( 2 equations with 2 variables at the same time)
( the (x, y) are the SAME in both equations)
The Substitution method-- allows you to get that answer without
graphing anything!
-just remember how to combine like terms and solve for a
variable!
