Question

Solve the system of equations using elimination. 4x - 7y = 5, 9x – 7y = –15 Responses A (3, 4)(3, 4) B (4, 3)(4, 3) C (-3, 4)(-3, 4) D (-4, 3)(-4, 3) E (-4, -3)

Answer 1

6x + 3y = 9 2x + 3y = 1 Solve the system of equations. Responses A x = 2, y = -1x = 2, y = -1 B x = -1, y = 2x = -1, y = 2 C x = - , y = 3x = - 1 2 , y = 3 D x = 3, y = - x = 3, y = -1/2 E x = 1, y = 1

Answer 2

Solve the system of equations using elimination. 8x + 7y = -16 10x + 7y = -6 Responses A (3, 6)(3, 6) B (8, 5)(8, 5) C (7, 10)(7, 10) D (5, -8)(5, -8) E (-5, -8)

Answer 3

5x - 2y = 3 -5x + 4y = 9 Solve the system of equations. Responses A x = 6, y = 3x = 6, y = 3 B x = 6, y = 13 1/2x = 6, y = 13 1 2 C x = 3, y = 6x = 3, y = 6 D x = 1, y = 0x = 1, y = 0 E x = -3, y = -6
