Question

1. Solve the system by using a table
-0.2x-0.3y=0.2
0.4x-0.3y=1.4
2.without graphing is the system independent dependent or inconsistent
Y=2x-8
2x-y=8
3.solve the system using an equivalent system
-2x-y=0
3x-y=10
4.what is the solution of the following system
-2x-y=10
-4x-2y=-1
5.solv the system by substitution
-4.5x-2y=-12.5
3.25x-y=-0.75
6.solve the system using elimination
5x+4y=12
3x-3y=18
