Chapter 8 test: solving systems of equations 1. solve by graphing
y= x-1

3x + 2y =8
the graph is up there lol

2. solve by substitution
x + 4y=6
y= -x+3

3. solve by elimination
x- 2y= -19
5x + 2y=1

4. solve by elimination
x + 3y= -2
3x + 4y= -1

5. solve the special system.

-2x + 8y= 5
x-4y= -3

6.
