(7, 3)
Elimination -x + y = -4 2x - 3y = 5
(-9, -4)
Elimination 3x - 5y = -7 -4x + 7y = 8
(1, -2)
Elimination 4x - 5y = 14 -4x + y = -6
(3, 5)
Elimination x + 2y = 13 x - 2y = -7
(-2, 5)
Elimination x + 6y = 28 2x - 3y = -19
(-2, 2)
Elimination x + 7y = 12 -2x + 7y = 18
(4, -1)
Graphing x + y = 3 x - y = 5
(2, -5)
Graphing y = -3x + 1 y = x - 7
(-1, 1)
Graphing y = 3x + 4 y = -2x - 1
(-3, -9)
Substitution 2x + y = -15 y - 5x = 6
(5, 1)
Substitution x + 4y = 9 x - y = 4
(3, -1)
Substitution y = 2x - 7 x + 2y = 1
