5.7 solving systems by elimination
solve each system by elimination.

1. ( x + 6y = -5 )

( -4x - 6y = 0 )

1. ( 4x + y = 23 )

( 3x - y = 26 )

1. ( -6x + 5y = -2 )

( 6x - 3y = 6 )

1. ( 6x + 4y = -4 )

( -6x + 8y = 28 )

1. ( -5x - 9y = 14 )

( -2x + 9y = -7 )

1. ( x + 3y = -19 )

( 3x - 3y = 15 )

1. ( 3x - 9y = 3 )

( -3x - 3y = -27 )

1. ( x - 2y = -10 )

( -7x + 2y = -14 )

1. ( 5x + 4y = -29 )

( -x - 4y = -7 )

1. ( -x + 8y = 24 )

( x - 4y = -16 )
