these are the last 3 problems on my take home test for the unit and i'm just not getting it:
by the substition method:
L1: -9x + 6y=2
L2: 3x - 2y=10
by the addition method:
L1: 3x - 2y=4
L2: -5x + y= -3
by any method:
L1: 3x - 2y=6
L2: 4x + 3y=8
also we have to show the work for the equations and show the work checking it as well
